WATCH: Trump assassination attempt latest, Diddy arrested | LiveNOW from FOX

The suspect in the second assassination attempt on former President Trump laughed and smiled ahead of his first court appearance in Florida on Monday, FOX News confirmed.

Ryan Wesley Routh, wearing jail scrubs and shackles on his wrists and ankles, walked into court and smiled and laughed about three to four times as he was speaking to his court-appointed attorney before the hearing began, FOX News observed. No cameras were permitted inside the federal court hearing regarding charges of possession of a firearm by a convicted felon and possession of a firearm with an obliterated serial number.

Routh appeared fully engaged and answered all the questions from the judge during the about 10-minute-long hearing Monday. He will be formally arraigned on Sept. 30.

FOX is told additional federal charges are possible. The initial charges announced Monday will keep Routh in custody.
