Tenure
Banks was sworn in on January 3, 2017. He is a member of the Republican Study Committee.
In December 2017, Banks joined representatives Ron DeSantis, Scott Perry, and Robert Pittenger in co-signing a letter to Secretary of State Rex Tillerson requesting that Tillerson release a classified counterterrorism agreement with Qatar.
In January 2020, Banks faced backlash after saying that remarks by Representative Ilhan Omar about her experiences with post-traumatic stress disorder were "offensive to our nation's veterans". As a child, Omar fled civil war in Somalia and spent four years in a Kenyan refugee camp.
In February 2021, Banks and a dozen other Republican House members skipped votes and enlisted others to vote for them, citing the ongoing COVID-19 pandemic. He and the other members were actually attending the Conservative Political Action Conference, which was held at the same time as their absences. In response, the Campaign for Accountability, an ethics watchdog group, filed a complaint with the House Committee on Ethics and requested an investigation into Banks and the other lawmakers.
In October 2021, Representative Liz Cheney, vice chair of the January 6 Select Committee, revealed that Banks had been sending letters to federal agencies, claiming to be the committee's ranking member even though he had been rejected from it. In one September 2021 letter, Banks requested that the Department of the Interior give him information it had sent the committee. He also wrote, "Pelosi refused to allow me to fulfill my duties as Ranking Member" and signed the letter as "Ranking Member", which he was not.
Also in October 2021, Business Insider reported that Banks had violated the Stop Trading on Congressional Knowledge (STOCK) Act of 2012, a federal transparency and conflict-of-interest law, by failing to properly disclose sales of stock in Kroger, Roblox, and Starbucks worth up to $45,000.
Also in October 2021, when Rachel Levine, who is transgender, became an admiral in the United States Public Health Service Commissioned Corps, Banks wrote in his official Twitter account: "The title of first female four-star officer gets taken by a man." Twitter, which at the time prohibited "targeted misgendering or deadnaming of transgender individuals", suspended his official account in response.
Shortly after Republicans retook control of the House of Representatives in the 2022 midterm elections, Banks ran for the position of Majority Whip, the third highest ranking position in the Republican caucus. He narrowly lost to Tom Emmer, 115–106.
In May 2023, Banks co-sponsored a resolution by Marjorie Taylor Greene to impeach Secretary of Homeland Security Alejandro Mayorkas.
