Herschel Walker, the Republican Nominee for US Senate from Georgia
Apparently Mr Walker is mentally ill.
As a Republican, this puts him in good company.
From wikipedia:
In June 2022, The Atlanta Journal-Constitution found Walker's claims about working in law enforcement were either false or unverifiable. Despite his claim of being an honorary deputy in the Cobb County Police Department, the department did not have any record of Walker working with them. In 2019, Walker said he "spent time at Quantico at the FBI training school" and was "an agent" when, in reality, Walker lacked the bachelor's degree required for FBI training. Previously, in 1989, Walker told the media that he "had fun" while attending an FBI school in Quantico for a week, speaking of an "obstacle course and you shoot at targets".
