Matt Gaetz of Florida to serve as United States Attorney General.In a post on Truth Social, Trump said that Gaetz would "root out the systemic corruption" at the Department of Justice.Gaetz quickly replied on X: "It will be an honor to serve as President Trump's Attorney General!"Hours after the announcement, House Speaker Mike Johnson told reporters that Gaetz had already resigned from Congress."I think out of deference to us, he issued his resignation letter, effective immediately, of Congress. That caught us by surprise a little bit," Johnson said, adding that by resigning now Congress may be able to fill Gaetz's seat by January 3.A spokesperson for Gaetz did not respond to a request for comment.The Attorney General is the country's top law enforcement official overseeing the Department of Justice and serving as a key legal advisor to the president.Gaetz's appointment will have to be confirmed by the US Senate, and there are plenty of reasons to believe it will be controversial.In more recent times, Gaetz has drawn backlash from fellow Republicans over his role in spearheading the ousting of Kevin McCarthy from the speakership last year, which led to weeks of chaos in the lower chamber.He is also likely to face renewed questions over sex-trafficking allegations, which arose after the Department of Justice opened an investigation into Gaetz in April 2021. Though the agency ultimately decline to pursue charges, the Florida congressman has continued to face a probe from the House Ethics Committee.A staunch Trump loyalist, Gaetz has been a relatively unusual figure in Washington.He's expressed admiration for Federal Trade Commission Chair Lina Khan, telling NOTUS earlier this year that he hopes "her work continues in the Trump administration." He also supports banning lawmakers from trading stocks and has touted his agreement with Democratic Rep. Alexandria Ocasio-Cortez on the issue.
