MSNBC’s Joe Scarborough on Thursday formally ended his tenure as a Republican by registering as an Independent.
The “Morning Joe” host announced the shift in political parties with a tweet mocking President Trump.
Scarborough revealed in a follow-up tweet that he was posing with the registrar of voters in New Canaan, Connecticut after switching political affiliations.
Scarborough’s tweet was referencing Trump’s past demands for former President Barack Obama to publicly release his birth certificate.
Trump helped popularize the so-called “birther” movement, which questions whether Obama was born in the U.S.
Scarborough was also resurfacing an incident last month when Trump named a nonexistent nation called “Nambia” while meeting with African leaders at the United Nations (U.N.).
The TV host announced in July that he was leaving the GOP while appearing on CBS’s The Late Show with Stephen Colbert.
“I am a Republican, but I’m not going to be a Republican anymore,” he told the late-night talk show host.
Scarborough’s decision followed Trump attacking the appearance of Mika Brzezinski, his “Morning Joe” co-host, on Twitter.
Trump said that Brzezinski was “bleeding badly from a face-lift” when the pair visited his Mar-a-Lago resort in Palm Beach, Florida on New Year’s Eve.
Brzezinski and Scarborough are now engaged and have become vocal critics of the GOP under Trump.
Scarborough served four terms as a GOP House representative for Florida before becoming a MSNBC anchor.
