Several colleagues told investigators about his wearing of a “Hitler mustache” while at work, court papers show.

An Army reservist charged in the Justice Department’s sweeping investigation of the U.S. Capitol riot was quietly demoted and discharged earlier this year, becoming the first known service member to be forced out of the military after officials learned of an alleged involvement in the Jan. 6 insurrection, according to personnel records reviewed by The Washington Post and the former soldier’s attorney.

Timothy Hale-Cusanelli, 31, was working part-time as an Army Reserve sergeant in human resources. In May, he was demoted to private — the enlisted force’s lowest rank — and given an other-than-honorable discharge the next month, terminating a 12-year military career, said his attorney Jonathan Crisp.

Federal authorities have accused Hale-Cusanelli of illegally entering the Capitol, using hand and arm signals to advance rioters forward and harassing police officers.
