The appointment of Gaetz as Attorney General was controversial even in the Republican camp.

Best to read the whole article but here's bits. His intentions are to control Justice politically
"In 2018, he brought a right-wing Holocaust denier to the State of the Union, and later tried to expel two fathers who lost children in a mass shooting from a hearing after they objected to a claim he made about gun control.
In a social media post, Trump spelled out how he intends to use Gaetz as a wrecking ball to radically change the US Department of Justice, which he has regularly blamed for his multiple legal troubles.
“Matt will root out the systemic corruption at the DOJ, and return the department to its true mission of fighting crime and upholding our democracy and constitution,” he wrote.
During the campaign, Trump promised retribution for the numerous investigations launched against him
Now, it appears, Gaetz will be at the frontlines of Trump’s efforts to bring the justice department to heel.
The department also investigated Gaetz himself.
Last year, it declined to bring charges over allegations he violated sex-trafficking laws during a trip he took to the Bahamas with paid escorts.
He was the subject of an ongoing ethics investigation in the House of Representatives into allegations of sexual misconduct, illicit drug use and misuse of campaign fund.
His bombastic approach means he has no shortage of enemies, including within his own party. And so Trump's choice of Gaetz for this crucial role is a signal to those Republicans, too - his second administration will be staffed by loyalists who he trusts to enact his agenda, conventional political opinion be damned.
