Morris Katz, a senior political adviser to Graham Platner, said he was “deeply disappointed” when he learned of the sexual assault allegations leveled against the U.S. Senate candidate in Maine that led to him dropping out of the race.

“As soon as the team became aware of the rape allegations against Graham Platner we advised he suspend his candidacy, and in the following days worked to wind down the campaign,” Katz said Thursday. “Like so many of his supporters, I’m deeply disappointed.”
