MSNBC host Joe Scarborough admonished Republicans who have celebrated the Justice Department’s indictment of former FBI Director James Comey.

“Republicans must understand that what goes around comes around,” Scarborough said Friday on his morning talk show. “They must understand that, if there’s a billionaire independent who decides to be president of the United States, gets elected and then decides to start going after Republicans.”

A critic of Trump and his allies, if elected president, Scarborough argued, could go after “Republican senators, Republican House members, Republican judges, Republican political operatives.”

“All that independent will have to do is just pick up the phone, call his or her attorney general and say, ‘arrest Republican senator A, arrest Republican political opponent B,” the host added in comments first highlighted by Mediaite, calling such a potential development “extraordinarily dangerous.”

Comey was indicted late Thursday on federal charges in connection with testimony he gave before the Senate in 2020 as it probed investigations into ties Trump’s 2016 campaign had with Russia.

Trump has for years dismissed “Russiagate” as a hoax and attacked Comey and others in federal law enforcement who he argued were out to get him ahead of his first presidential election.

Comey in a social media post after his indictment wrote he is “not afraid” of the charges he faces and said his “heart is broken for the Department of Justice, but I have great confidence in the federal judicial system.”

While Trump celebrated the Justice Department’s moves and called the ex-FBI chief a “bad cop,” Democrats have come out in support of Comey and argued that a conviction is unlikely.
