The FBI has named 66-year-old James T. Hodgkinson of Belleville, Illinois, as the suspect in the congressional baseball practice shooting on Wednesday morning.

House Majority Whip Steve Scalise was among several people shot, and "was critically injured and remains in critical condition," MedStar Washington tweeted Wednesday afternoon. He had undergone surgery earlier that day.

President Donald Trump said the gunman who carried out the attack had died.

The shooting occurred in Alexandria, Virginia, just outside of Washington, DC.

Police arrived on the scene within three minutes and fired multiple shots at the gunman, officials said. Two Capitol Police officers, who were part of Scalise's security detail, were also injured in the shooting.

The FBI and police officials said they would not yet share any information about the suspect's motivation at a press conference. The FBI special agent in charge of the Washington field office said it was too early to rule out terrorism, or whether the gunman deliberately targeted Republican members of Congress.

Scalise's office said in a statement that the congressman is in stable condition at MedStar Washington Hospital. He was shot in the hip and is undergoing surgery, the statement said.

"The FBI is actively investigating Hodgkinson to include his associates, whereabouts, social media impressions, and potential motivations. This is an active investigation that continues to unfold," the FBI said in a statement.

What we know about the suspect

Hodgkinson's wife told ABC that he had been living in Alexandra for the past two months.

A Facebook page linked to Hodgkinson lists him as the owner of JTH Inspections. A Yelp page for JTH Inspections has pictures of Hodgkinson and locates the company in Belleville, IL.

Hodgkinson posted content favorable to Democratic presidential candidate Bernie Sanders on his page and signed a Change.org petition for the removal of Trump and Vice President Mike Pence.

"Trump is a Traitor. Trump Has Destroyed Our Democracy. It's Time to Destroy Trump & Co.," Hodgkinson wrote in a March 22 post.

Hodgkinson also maintained a Twitter profile with the handle @JTHInspections.

Court records show that Hodgkinson was arrested in 2006 on charges of battery and aiding damage to a motor vehicle, but the charges were dismissed, The Washington Post reported.
