On May 23, 2023, Luna co-sponsored resolutions to impeach Attorney General Merrick Garland, FBI director Christopher Wray, Secretary of Homeland Security Alejandro Mayorkas, and U.S. attorney for D.C. Matthew M. Graves.
On June 21, 2023, Luna sponsored a resolution censuring Democratic representative Adam Schiff for his past actions as chair of the House Intelligence Committee in leading investigations into then-president Donald Trump. The House agreed to the resolution with a vote of 213–209.
On July 10, 2024, Luna brought forward a privileged resolution to have U.S. attorney general Merrick Garland found in inherent contempt of Congress. The resolution would have imposed a fine of $10,000 per day on Garland for defying a congressional subpoena. The measure failed to pass in a 204 to 210 vote.
In the 118th Congress she co-sponsored a pair of resolutions meant to expunge the impeachments of Donald Trump. In the 119th United States Congress, she again co-sponsored resolutions to expunge Trump's impeachments.
In January 2025, Luna introduced a bill proposing to add Trump's face to Mount Rushmore.
In March 2025, Luna worked with Rep. Brittany Pettersen (D), some other Democrats and some Republicans to force a vote on a bill through a discharge petition which would allow new parents to vote by proxy. The petition angered members of the Freedom Caucus, who believe that proxy voting is unconstitutional, and led them to initially vote against a procedural rules vote on Republican supported energy bills. After negotiations with House Republican leadership, the Freedom Caucus would later allow the vote to pass. Freedom Caucus leadership urged Republican leadership to raise the threshold required to force a vote on a bill through a discharge petition. Luna would later resign from the Freedom Caucus. In a letter, she said her decision to resign was due to the loss of "mutual respect that has guided our caucus." On April 1, Republican leadership attempted to pass a rule vote that would prevent Luna's bill from being voted on. Nine Republicans (Luna, Tim Burchett, Mike Lawler, Kevin Kiley, Nick LaLota, Jeff Van Drew, Max Miller, Greg Steube and Ryan Mackenzie) joined all Democrats to block the rule vote. On April 6, Luna and Johnson reached an agreement that would allow absent members to use vote pairing. Their intended vote will still be published in the Congressional Record.
In September 2025, Luna criticized the Anti-Defamation League for listing Christian Identity, a white supremacist and antisemitic religious ideology, as extremist. The criticism came after Elon Musk negatively commented on a screenshot of the ADL's page on Christian Identity. Luna claimed the ADL was "intentionally creating a targeted hate campaign against Christians."
Following the 2025 Brown University shooting, Luna amplified a theory misidentifying a Palestinian student at Brown University as the perpetrator. A different individual, Claudio Manuel Neves Valente, was subsequently identified as the shooter.
In March 2026, Luna hosted a delegation of visiting Russian lawmakers on a tour of the United States Capitol. Luna's hosting was criticized by fellow congressional lawmakers, including her Republican colleagues.
In June 2026, Luna submitted an amendment to the National Defense Authorization Act. Luna's summary of the amendment was copied and pasted from Claude AI, with the summary including the phrase "Claude responded." Luna defended her use of AI, saying most congressional staff members used AI.
Luna held a hearing in June 2026 on MKULTRA, the defunct CIA failed mind control program. Luna had previously shared an article from the Daily Mail titled "Declassified CIA files reveal chilling blueprint to manipulate Americans' minds through covert drugging with vaccines". During the hearing, Luna said the CIA was declassifying newly discovered files on MKULTRA and suggested, without evidence, that USAID may have been involved in MKULTRA operations overseas.
In July 2026, the Wall Street Journal said a source had told it that, during the 2024 United States presidential election, Luna said she had tipped off conservative influencer Rogan O'Handley that Trump had selected JD Vance as his running mate so that O'Handley could place a winning wager on Polymarket. Luna reportedly teased O'Handley for not placing a bigger wager. Luna said she did not know beforehand that Vance had been selected as Vice President and O’Handley said he had not received, traded on or discussed nonpublic information about Trump’s vice presidential pick. A source told the WSJ that the United States Commodity Futures Trading Commission(CFTC) opened an investigation into the allegation after receiving a report. Luna lodged a criminal complaint with the CFTC, stating that the report made to the agency was knowingly false.
