"We also assessed that there is no nexus to terrorism". The police shot Hodgkinson at the scene, and he later died of his injuries.
The FBI also said that Hodgkinson visited a storage facility in Alexandria more than 43 times between April and June. On the morning of the shooting, Hodgkinson had asked a witness near the field if it was Democrats or Republicans playing.
Two days before the shooting, a family member said Hodgkinson sent a message about coming back home to IL. Another U.S. Capitol Police officer was struck by shrapnel, and Rep. Roger Williams (R-Tex.) injured his ankle while helping others take cover. Slater said it did not appear to be a "hit list", though Hodgkinson had done "cursory" searches of at least two of the politicians on his list.
The gunman who shot four people including a Republican member of Congress at a baseball field last week acted alone and was not connected to terrorism, FBI investigators said Wednesday.
Representative Steve Scalise, the House majority whip, was gravely wounded in the shooting last week.
Congressman Scalise has undergone several surgeries and remains hospitalized, but he continues to improve.
Hodgkinson visited the office of Sen.
"Here's a Republican that should lose his job, but they gave him a raise", Hodgkinson purportedly wrote at the time, referring to the Louisiana congressman.
Slater said Hodgkinson "suffered from taking some prescription medication".
The night before the shooting, Hodgkinson did a Google search for the "2017 Republican Convention", the Federal Bureau of Investigation said.
In March, Hodgkinson left IL and drove to Alexandria, Virginia, where he lived in his van in a YMCA parking lot.
Slater said Hodgkinson legally purchased both the guns he used in the attack - the handgun in March 2003 and the rifle in November 2016, after the presidential election.
The group of lawmakers and staffers were practising for a charity game against a team of Democrats that was played the next day and raised over US$1 million (S$1.39 million). U.S. Capitol Police and other officers returned fire and killed the gunman, who turned out to be an unemployed home inspector with a deep animus toward President Donald Trump and other Republicans.
Watson said he learned of Hodgkinson's connection to the Virginia shooting shortly after 9:30 a.m., when he arrived at the department for a meeting.
Officials noted that the gunman posted numerous items on social media accounts "espousing anti-Republican views, although all of the posts reviewed thus far appear to be First Amendment-protected speech".
Scalise, who was shot in the hip, was at "imminent risk of death" when arrived at D.C. MedStar Washington Hospital Center, doctors said last week.
He exited his auto last Wednesday carrying two weapons - the SKS rifle that had been modified to use a detachable magazine and a folding stock, and a 9mm handgun in a holster - that had been bought legally, Slater said.
