According to BBC, he is also being charged with counts such as using a firearm and transporting a firearm across state lines with the intent to commit a serious crime. Under these charges, he faces up to 10 years in prison, and if found guilty of attempting to assassinate the President, he could face life imprisonment. For now, Allen denies all charges.
According to the prosecution, he crossed several states to carry out the attack. A 12-gauge pump shotgun, three knives, and other weapons were found on him.
The incident occurred on the night of April 26 in the banquet hall of the Washington Hilton hotel. Allen, a 31-year-old California resident, had booked a room at the hotel and fired shots at a U.S. Secret Service agent near the entrance of the hall. He was apprehended at the scene.
Later, Donald Trump speculated that the attack was not linked to Iran.
