The FBI released new information Wednesday on the shooting at the Republican congressional baseball game last week, and said it "does not believe there is a nexus to terrorism."
Authorities reported that James Thomas Hodgkinson, 66, had a list of six congressmen's names in his possession during the time of the shooting.
Two Republican lawmakers had told authorities that before the shooting, Hodgkinson asked if those on the baseball field were Democrats or Republicans.
Hodgkinson told a family member in March that he was traveling to Washington, D.C., authorities said, but he did not provide any additional information on his travel.
The FBI found that Hodgkinson posted anti-Republican sentiments on his social media accounts. He also looked up maps of the area where the shooting occurred.
While announcing the recent developments, authorities stressed that the shooting is still an ongoing investigation.
