Bryson, 68, who has been in office since October, was found unconscious in his Lexus June 9, after the second of two collisions, police said. He had a seizure, according to his office. He took medical leave June 11.
In a letter to the agency today, he said he was resigning to prevent his situation from becoming a distraction to the agency.
Bryson’s crashes put him in danger of felony charges, though word about having a seizure behind the wheel only came out after the story about the initial crash did.
