His announcement comes after President Trump launched an attack on Scarborough and “Morning Joe” co-host Mika BrzezinskiMika Emilie BrzezinskiOcasio-Cortez defends being sworn in at hearing on conditions for migrants Mika Brzezinski to Ivanka and Melania: 'You will go down in history as having done nothing about' conditions for migrant children Scarborough: D-Day anniversary speech 'most powerful' of Trump's presidency MORE in late June.

Trump went after Brzezinski’s appearance, saying that she was “bleeding badly from a face-lift” when she and Scarborough visited Trump's Mar-a-Lago club on New Year’s Eve.

The "Morning Joe" duo fought back, saying that White House staff told them that Trump would have a tabloid story run about them unless they “begged” for it to be killed. Scarborough said he had evidence to back these claims but that he wouldn’t release it.

Trump was once a regular guest on "Morning Joe," when the co-hosts were accused of having a cozy relationship with the then-candidate during the GOP presidential primary. But the relationship soured, and Trump began feuding with the MSNBC hosts.

The Republican National Committee also targeted the show in May, calling it “the worst case of Trump Derangement Syndrome.”
