Collins opposed the [[Women's Health Protection Act]]. In procedural issues, she has maintained her support for the 60-vote Senate threshold, arguing for bipartisan compromise and preserving the [[Filibuster in the United States Senate|filibuster]]. Collins was a pivotal Republican vote for the [[Trump administration]]'s [[Tax Cuts and Jobs Act]], though she later expressed concern about some of its provisions.

During the [[impeachment trial of Bill Clinton]], Collins was one of the few Republican senators who voted to acquit him on both charges. During the [[first impeachment trial of Donald Trump]], Collins joined most other Senate Republicans in voting to acquit on both charges. In his [[Second impeachment trial of Donald Trump|second impeachment trial]], she was one of seven Republicans to vote to convict Trump of [[Sedition|incitement of insurrection]].

In [[2020 United States Senate election in Maine|2020]], Collins was challenged by Democratic State House Speaker [[Sara Gideon]].

===Tenure===
====First term====

In the 1990s, Collins played an important role during the Senate's [[Clinton impeachment|impeachment trial]] of [[Bill Clinton]] when she and Snowe sponsored a motion that would have allowed the Senate to vote separately on the charges and the sentence.{{citation needed|date=November 2024}} The motion failed, and Snowe and Collins voted to acquit, believing that while Clinton had committed [[perjury]], that was not grounds for removal from office.<ref>{{cite web |title=How the senators voted on impeachment |url=https://www.cnn.com/ALLPOLITICS/stories/1999/02/12/senate.vote/ |date=February 12, 1999 |website=[[CNN]] |access-date=November 17, 2019}}</ref>

In March 1997, the Senate adopted a broader investigation into White House and congressional campaign fund-raising practices than Senate Republicans initially wanted. Collins said there were "a number of allegations that may or may not be illegal, but they may be improper."<ref>{{cite news|url=https://www.nytimes.com/1997/03/12/us/senators-endorse-campaign-inquiry-with-wider-scope.html|title=Senators Endorse Campaign Inquiry with Wider Scope |first=Eric|last=Schmitt|date=March 12, 1997|work=[[The New York Times]]|access-date=September 15, 2020 }}</ref>

In a May 1997 interview, Collins stated her support for a proposal by [[Tom Daschle]] banning all abortions after the fetus is capable of living outside the womb except to save the life of the woman or protect her from physical injury. Of an alternative measure proposed by [[Rick Santorum]] that would ban partial-birth abortion, Collins said it "ignores cases in the medical literature involving women with very serious physical health problems".<ref>{{cite news|url=https://www.nytimes.com/1997/05/13/us/senate-is-lacking-veto-proof-vote-for-ban-on-an-abortion-method.html |first=Katherine Q. |last=Seelye |title=Senate Is Lacking Veto-Proof Vote for Ban on an Abortion Method|date=May 13, 1997|work=[[The New York Times]]}}</ref>

In 2001 Collins authored a measure that granted the [[United States Secretary of Education]] authority to grant waivers that would relieve reservists and members of the [[United States National Guard|National Guard]] from making federal student loan payments during active duty and grant the same privileges to victims and families of those affected by the [[September 11 attacks]]. The bill passed the Senate and House in December 2001.<ref>{{cite news|url=https://www.michigansthumb.com/news/article/Student-Loan-Bill-Goes-to-President-7376214.php|title=Student Loan Bill Goes to President|date=December 19, 2001|publisher=michigansthumb.com}}</ref>

In November 2002, the Senate overwhelmingly approved the creation of the [[United States Department of Homeland Security|Department of Homeland Security]] while a Democratic effort to remove the bill's provisions fell short on a 52-to-47 vote that came after President [[George W. Bush]] lobbied against the vote. Collins and other senators said that Senate and House Republicans, as well as the White House, had given them an "ironclad promise" to essentially rescind provisions in the first spending bill to pass Congress the following year.<ref>{{cite news|url=https://www.nytimes.com/2002/11/20/us/threats-responses-legislation-senate-votes-90-9-set-up-homeland-security-dept.html|title=THREATS AND RESPONSES: LEGISLATION; SENATE VOTES, 90–9, TO SET UP A HOMELAND SECURITY DEPT.

====Second term====

In 2004, Collins was one of the primary sponsors of legislation overhauling the U.S. intelligence community by creating a new post, [[Director of National Intelligence]], to oversee budgets and most assets of the spy agencies, and mandating that federal agencies establish minimum standards for states pertaining to issuing driver's licenses and birth certificates along with directing the [[United States Department of Homeland Security]] to form standards for ID used to board airplanes. The bill passed in the House and Senate in December. Collins said, "This was the most difficult bill to bring from conception to birth that I can imagine being involved with. But that makes the victory doubly satisfying."<ref>{{cite news|url=https://edition.cnn.com/2004/ALLPOLITICS/12/08/intelligence.bill/index.html |title=Senate OKs intelligence overhaul bill|date=December 10, 2004|work=[[CNN]]}}</ref> Bush signed the bill, formally known as the [[Intelligence Reform and Terrorism Prevention Act]], on December 17, 2004.<ref>{{cite news|url=https://www.nytimes.com/2004/12/17/politics/bush-signs-bill-to-revamp-us-intelligence-community.html|title=Bush Signs Bill to Revamp U.S. Intelligence Community|author=Stout, David|date=December 17, 2004|work=[[The New York Times]]|access-date=September 18, 2020}}</ref>

In May 2005, Collins was one of [[Gang of 14|14 senators]] (seven Democrats and seven Republicans) to forge a compromise on the Democrats' use of the judicial [[filibuster]], thus allowing the Republican leadership to end debate without having to exercise the [[nuclear option]]. Under the agreement, Democrats agreed they would filibuster Bush's judicial nominees only in "extraordinary circumstances"; three Bush [[appellate court]] nominees ([[Janice Rogers Brown]], [[Priscilla Owen]], and [[William H. Pryor Jr.|William Pryor]]) would receive a vote by the full Senate; and two others, [[Henry Saad]] and [[William Myers (lawyer)|William Myers]], were expressly denied such protection (both eventually withdrew their names from consideration).<ref>{{cite news|url=https://edition.cnn.com/2005/POLITICS/05/24/filibuster.fight/ |title=Senators compromise on filibusters: Bipartisan group agrees to vote to end debate on 3 nominees |work=[[CNN]] |date=May 24, 2005 }}</ref><ref>{{cite news |first=Ken |last=Rudin |url=https://www.npr.org/templates/story/story.php?storyId=5080836 |title=Judging Alito: The Gang of 14 Factor |website=[[NPR]]|date=January 4, 2006 }}</ref>

In October 2008, Collins criticized robocalls by the McCain campaign claiming that [[Barack Obama]] "has worked closely with domestic terrorist [[Bill Ayers]], whose organization bombed the U.S. Capitol, the Pentagon, a judge's home and killed Americans", asserting that those "kind of tactics have no place in Maine politics" and urging McCain to cease the calls immediately.<ref>{{cite news|url=https://www.latimes.com/archives/la-xpm-2008-oct-18-na-robo18-story.html |agency=Associated Press |title=GOP senator decries anti-Obama robocalls|date=October 18, 2008|work=[[Los Angeles Times]]}}</ref>

====Third term====

In 2009, Collins played a role in removing $870 million in pandemic flu funding from a $787 billion stimulus package. She said she had done so on procedural grounds: "It is the regular appropriations process that is the appropriate vehicle for considering funding for many of these programs that, while worthwhile, do not boost our economy."<ref>{{cite news |last1=Dennis |first1=Steven |title=Sen.

In April 2010, Collins and Senator [[Joe Lieberman]] issued a subpoena seeking documents and interviews associated with the American government's investigation into the conduct of investigators during their interactions with [[Nidal Hasan]] before the [[2009 Fort Hood shooting|Fort Hood shooting]]. The Pentagon announced that the Obama administration would not authorize Senate investigators to question intelligence agents who reviewed e-mails between Hasan and an extremist Islamic cleric before the shooting. Collins and Lieberman issued a statement accusing the Departments of Justice and Defense of refusing "to provide access to their agents who reportedly reviewed Major Hasan's communications with radical extremist cleric Anwar al Awlaki and to transcripts of prosecution interviews with Hasan's associates and superiors, which DOD already provided to its internal review."<ref>{{cite news|url=https://www.mcclatchydc.com/news/politics-government/article24581011.html|title=Senators disappointed by response to Fort Hood subpoena|date=April 27, 2010|publisher=mcclatchydc.com}}</ref>

In May 2010, Collins and Snowe were the only two Republicans to vote for an unsuccessful Democratic measure that would have prevented bailouts, highlighted financial products of complexity and toughened consumer protection.<ref>{{cite news|url=https://money.cnn.com/2010/05/19/news/economy/Wall_Street_reform/index.htm|title=Wall Street reform fails test|first=Jennifer|last=Liberto|date=May 19, 2010|work=[[CNN]]}}</ref>

In February 2013, Collins announced her opposition to the confirmation of [[Chuck Hagel]] for [[United States Secretary of Defense]], citing her belief that Hagel's "past positions, votes and statements [do not] match the challenges of our time." The announcement came as a surprise, as Collins was considered a possible supporter of his nomination, and it occurred while the nomination was being filibustered.<ref>{{cite news|url=https://www.usatoday.com/story/news/politics/2013/02/13/hagel-defense-secretary-susan-collins/1917369/|title=Senate gets ready for Chuck Hagel showdown|first=Catalina|last=Camia|date=February 13, 2013|publisher=[[USA Today]]}}</ref> The filibuster on Hagel's nomination was defeated,<ref>{{cite web |title=Senate Allows Nomination Of Chuck Hagel To Move Forward|url=https://www.npr.org/sections/thetwo-way/2013/02/26/172971326/senate-allows-nomination-of-chuck-hagel-to-move-forward |date=February 26, 2013 |first=Eyder |last=Peralta |publisher=[[NPR]]}}</ref> and he was confirmed later that month.<ref>{{cite news|title=Chuck Hagel confirmed as US defence secretary by Senate|url=https://www.bbc.com/news/world-us-canada-21591701 |work=[[BBC News]]|access-date=September 15, 2020 |date=February 27, 2013}}</ref>

In May 2013, following a report that the Internal Revenue Service had put additional scrutiny on conservative groups, Collins said the revelation "contributes to the profound distrust that the American people have in government" and added that she was disappointed that Obama "hasn't personally condemned this and spoken out".<ref>{{cite news|url=https://edition.cnn.com/2004/ALLPOLITICS/12/08/intelligence.bill/index.html |title=Collins says IRS revelations will fuel government distrust|date=May 12, 2013 |access-date=September 15, 2020 |work=[[CNN]]}}</ref>

In April 2014, the Senate debated the [[Minimum Wage Fairness Act (S. 1737; 113th Congress)]]. The bill would have amended the [[Fair Labor Standards Act of 1938]] (FLSA) to increase the federal minimum wage to $10.10 per hour over two years.<ref name=1737sum>{{cite web|title= S. 1737 – Summary|date=April 2, 2014 |url=https://www.congress.gov/bill/113th-congress/senate-bill/1737 |publisher=United States Congress|access-date=April 8, 2014}}</ref> The bill was strongly supported by Obama and many Democratic senators but strongly opposed by Republicans in the Senate and House.<ref name=ObamaClearChoice>{{cite news|last=Sink|first=Justin|title= Obama: Congress has 'clear choice' on minimum wage|url=https://thehill.com/blogs/blog-briefing-room/news/202475-obama-congress-has-clear-choice-on-minimum-wage |access-date=April 9, 2014|newspaper=[[The Hill (newspaper)|The Hill]]|date=April 2, 2014}}</ref><ref name=Reidpunts>{{cite news|last=Bolton|first=Alexander|title= Reid punts on minimum-wage hike|url=https://thehill.com/homenews/senate/202964-reid-punts-on-minimum-wage-hike |access-date= April 9, 2014|newspaper=[[The Hill (newspaper)|The Hill]]|date=April 8, 2014}}</ref><ref name=CentristRepubs>{{cite news|last=Bolton|first=Alexander|title=Centrist Republicans cool to minimum wage hike compromise|url=https://thehill.com/homenews/senate/202641-centrist-republicans-cool-to-wage-compromise|access-date=April 9, 2014|newspaper=[[The Hill (newspaper)|The Hill]]|date=April 4, 2014}}</ref> Collins tried to negotiate a compromise bill that centrist Republicans could agree to but was unable to do so.<ref name=CentristRepubs />

In May 2016, the Senate passed an appropriations bill containing an amendment by Collins that she said would help prevent the [[United States Department of Housing and Urban Development|Department of Housing and Urban Development]] from gaining "national zoning authority for every neighborhood in our country". The legislation was given a veto threat by the White House, which was said by the Office of Management and Budget to oppose "the inclusion of problematic ideological provisions that are beyond the scope of funding legislation".<ref>{{cite news|url=https://thehill.com/blogs/floor-action/senate/280586-senate-approves-transportation-veterans-appropriations-bill |first=Jordain |last=Carney |title=Senate passes broad spending bill with $1.1B in Zika funds|date=May 19, 2016|work=[[The Hill (newspaper)|The Hill]]}}</ref>

In 2016, Collins authored the Safe Treatments and Opportunities to Prevent Pain Act, a provision intended to encourage the [[National Institutes of Health]] to further its research into opioid therapy alternatives for pain management, and the Infant Plan of Safe Care Act, which mandated that states ensure safe care plans are developed for infants who are drug-dependent before they are discharged from hospitals.

On August 8, 2016, Collins announced that she would not vote for [[Donald Trump]], the Republican nominee in the [[2016 United States presidential election|2016 presidential election]]. She said that as a lifelong Republican she did not make the decision lightly but felt he was unsuitable for office, "based on his disregard for the precept of treating others with respect, an idea that should transcend politics".<ref>{{cite news|url=https://www.washingtonpost.com/opinions/gop-senator-why-i-cannot-support-trump/2016/08/08/821095be-5d7e-11e6-9d2f-b1a3564181a1_story.html |first=Susan |last=Collins |access-date=September 14, 2020 |title=GOP senator Susan Collins: Why I cannot support Trump|date=August 8, 2016|newspaper=[[The Washington Post]]}}</ref> She considered voting for the [[Libertarian Party (United States)|Libertarian Party]]'s ticket or a [[write-in candidate]].<ref>{{Cite news|url=https://www.boston.com/news/politics/2016/08/09/echoing-romney-susan-collins-says-she-would-vote-for-the-libertarian-ticket-if-bill-weld-were-the-nominee |first=Nik |last=DeCosta-Klipa|title=Echoing Romney, Susan Collins says she would vote for the Libertarian ticket if Bill Weld were the nominee|date=August 9, 2016|work=Boston.com|access-date=January 2, 2019|language=en-US}}</ref><ref>{{cite web|url=https://wgme.com/news/local/sen-susan-collins-considers-libertarian-write-in-for-persident |date=August 14, 2016 |title=Susan Collins considers Libertarian, write-in for president|website=[[WGME-TV]] |first=Daniel |last=Lampariello |language=en-US|access-date=January 2, 2019}}</ref>
