Jeff Duncan


Jeff Duncan (R-S.C.) has represented South Carolina’s 3rd Congressional District in the U.S. House of Representatives since 2011. A member of the House Freedom Caucus and among the leaders of the House Republican Committee, he ran for reelection in 2022 unopposed and had Trump’s endorsement.

Prior to running for Congress, Duncan managed his family-owned real estate marketing firm and served as a member of the South Carolina House of Representatives from 2002–10.

In Congress, Duncan has been among the most strident gun rights advocates, sponsoring legislation to expand concealed carry laws and warning against a federal gun registry, which he claimed could be used by liberals to hunt down gun owners in the same way “the Hutus slaughtered the Tutsis in Rwanda.”

After the 2020 presidential election, Duncan helped spread the Big Lie, objected to certifying the Electoral College results, and voted against both impeaching Trump for inciting the mob and establishing a special House committee to investigate the insurrection, among other measures. 

January 6, 2021

  • Just hours after Trump supporters stormed the Capitol, Duncan joined 146 other congressional Republicans in refusing to certify Biden’s win of the 2020 presidential election.
  • Duncan opposed impeaching Trump for his role in inciting the insurrection, calling it a “rushed, political stunt [that] made a mockery of what the impeachment process should be—solemn and methodical.”
  • Duncan voted against establishing a House committee to investigate the Jan. 6 attack. 

The Big Lie

  • On Nov. 6 and Dec. 1, 2020, Duncan signed letters from fellow House Republicans to Attorney General Bill Barr urging the Justice Department to investigate irregularities and accusations of fraud in the 2020 presidential election.
  • On Dec. 10, 2020, Duncan signed an amicus brief in a lawsuit filed by the state of Texas urging the U.S. Supreme Court to overturn the results of the presidential election in four swing states: Georgia, Michigan, Pennsylvania, and Wisconsin.
  • On Dec 31, 2020, Duncan tweeted that he would reject the certification of elections in Arizona, Georgia, Michigan, Nevada, Pennsylvania, and Wisconsin because of “unprecedented institutional issues, like states changing their voting systems in violation of their state constitutions….” 
  • He released a statement on Jan. 7, 2021 justifying his decision to vote against certifying Biden’s Electoral College victory because “the assault on the Capitol did not change the substance of the issues at hand. And that is why—even after the chaos—I raised objections to electors from certain states that performed elections in clear violation of Article II, Section 1 of the Constitution.” 
  • On Apr. 3, 2021, Duncan tweeted: “An overwhelming bipartisan majority of Americans support requiring an ID to vote, and any organization that abuses its power to oppose secure elections deserves increased scrutiny under the law.”
  • In December 2021, Duncan introduced legislation known as the Protecting Our Democracy by Preventing Foreign Citizens from Voting Act, which would prohibit the disbursement of federal funds to state and local governments that allow non-U.S. citizens to vote.
  • When Major League Baseball (MLB) moved the All Star Game out of Atlanta in 2021 to protest Georgia’s repressive voter laws, Duncan began drafting legislation to revoke the MLB’s federal antitrust exemption.
