WASHINGTON (AP) — GOP House Whip Steve Scalise “will be in the hospital for some time,” according to the facility where he is recovering from a gunshot. His House colleagues paid tribute to him at their annual charity baseball game, while law enforcement tracked the path the shooter traveled to his ballfield carnage.

Investigators studying Wednesday’s attack at a suburban Virginia park says shooter James Hodgkinson, a Belleville, Illinois, home inspector, had obtained his rifle and handgun from licensed firearms dealers. Capitol Police say they have “no evidence to suggest that the purchases were not lawful.”

As congressional Republicans and Democrats joined Thursday night in their baseball game, played this year in Scalise’s honor, word came from the hospital that he remained in critical condition, but had “improved in the last 24 hours.”
