A former Tennessee police officer who was arrested outside the White House on Sunday had a cache of weapons in his car and told authorities he came for help removing a chip he thought had been implanted in his head, according to court documents.

Court records show he was allowed to retire early because of medical issues.

An arrest affidavit says Bates was committed for mental health issues in February.
