In June 2020, after a Politico investigation resurfaced what it described as "Facebook videos in which [Greene] expresses racist, Islamophobic and anti-Semitic views," House Minority Leader Kevin McCarthy (R-Calif.), House Republican Conference Chairwoman Liz Cheney (R-Wyo.), and National Republican Congressional Committee (NRCC) Chairman Tom Emmer (R-Minn.) condemned Greene's remarks, with a spokesman for the NRCC saying the Chairman is "personally disgusted by this rhetoric and condemns it in the strongest possible terms." Greene responded to the criticism in a July 19 debate, saying: "I think you're aware that if you're a Republican and you are unapologetically conservative like I am, you're going to see people like me called a racist even when it's very unwarranted."

Congress convened a joint session on January 6-7, 2021, to count electoral votes by state and confirm the results of the 2020 presidential election. Greene voted against certifying the electoral votes from Arizona and Pennsylvania. The House rejected both objections by a vote of 121-303 for Arizona and 138-282 for Pennsylvania.

On February 4, 2021, the House of Representatives voted 230-199 to remove Greene from her assignments on the Labor and the Budget and Education committees. The vote was a response to multiple controversial remarks made by the first-term lawmaker, including a claim that school shootings are staged events. The House Rules Committee voted to advance the resolution on February 3 after Republican leadership declined to take action on her comments. Before the vote, Greene addressed the House floor. “These were words of the past and these things do not represent me, they do not represent my district, and they do not represent my values,” she said. Greene also apologized to her Republican colleagues during a closed-door meeting the previous day.
