 Fox's CB Cotton has more on the suspect, whose name is Thomas Matthew Crooks. Crooks was shot and killed by Secret Service. The Associated Press reports the political leanings of the gunman aren't clear at this time, citing records of his registration as a Republican voter here in Pennsylvania, with federal campaign finance reports showing Crooks gave 15 bucks to a progressive political action committee. Republican Speaker Mike Johnson says the House will conduct a full investigation.
