A prominent New Jersey Republican has denounced Donald Trump as a 2024 presidential candidate following surprise testimony at the Jan. 6 Select Committee hearings this week.

Former Gov. Tom Kean Sr. says that Trump is not fit to serve again as president.

Kean was also the former chairman of the 9/11 Commission. He spoke on News 12 New Jersey’s Power & Politics show, reacting to the testimony of former White House aide Cassidy Hutchinson.

Hutchinson testified that Trump knew participants of the mob at the United States Capitol were armed and that he wanted to go to the Capitol to join them, but Secret Service told him it was not safe.

“The facts are very, very disturbing because it looks like he was unhinged at times. And that's scary in an American president,” Kean says. “Look, a lot of the things Donald Trump did as president I supported. But this presents a human being that is not in fully control of himself, let alone the country. If this is all accurate, then it's very, very disturbing.”

Hutchinson was raised in Pennington and graduated from Hopewell Valley Central High School.

Kean says he believes that she is a “credible” witness.
