President Donald Trump trashed Don Lemon and denied having advance knowledge that the ex-CNN host would be arrested last week.

Federal authorities arrested Lemon on Thursday evening on federal civil rights charges in connection with his coverage of a protest at Cities Church in St. Paul, Minn., on Jan. 18. The charges included conspiracy and hampering the First Amendment rights of those worshiping at the church.

According to Los Angeles Mayor Karen Bass, Lemon was ”released on his own recognizance.” His next court date is Feb. 9 in Minneapolis.

While talking with reporters on Air Force One on Saturday, Trump said Lemon’s arrest was “the best thing that could happen to him” in his decades-long journalism career.

When a reporter asked if he knew Lemon was going to be taken into custody, Trump said that he didn’t “know anything about the Don Lemon thing,” then described him as a “sleazebag.”
