Suspected Charlie Kirk shooter Tyler Robinson used Donald Trump’s name as a pseudonym on Valve Corp’s Steam video-game platform, a fact that’s become part of a profile US law enforcement is building on the alleged assailant.
The US Secret Service has joined the investigation into the shooting, even though Kirk wasn’t under the agency’s protection, according to the people with knowledge of the matter.
