Outgoing Maryland Gov. Larry Hogan slammed GOP gubernatorial nominee Dan Cox as a nut who has no chance whatsoever of winning the November election.

The term-limited GOP governor, during an interview with WGMD radio on Wednesday, condemned his partys Donald Trump -backed nominee for attacking former Vice President Mike Pence during the Jan. 6 riot, The Washington Post reported .

Hes not, in my opinion, mentally stable, Hogan said in the interview. He wanted to hang my friend, Mike Pence, and took three busloads of people to the Capitol.

Cox, tweeted Pence is a traitor during the riot, and later deleted the tweet, the Frederick News-Post reported .

Hogan, a popular governor frequently at odds with Trump, backed Coxs primary opponent Kelly Schulz before her loss last month. He has been outspoken about Cox in the past, once calling him a QAnon whack job.
