James Hodgkinson, the man who attacked Republican members of Congress at a baseball practice Wednesday morning, railed against the "one percent" in a 2011 interview.
The 66-year-old was interviewed at an Occupy rally in St. Louis by local station KTVI.
"The 99 percent are getting pushed around and the one percent don't give a damn. So, we've got to speak up for the whole country," he told the station.
Hodgkinson, a native of Belleville, Illinois, supported Bernie Sanders and routinely blasted Republicans and President Trump on social media.
The FBI said Hodgkinson opened fire on the lawmakers and aides at the Alexandria, Virginia, baseball field, critically wounding House Majority Whip Steve Scalise (R-LA).
He was killed in a shootout with Capitol Hill police officers who were at the field to protect Scalise.
Earlier on "Fox & Friends," Rep. Mike Bost (R-IL) said the gunman had contacted his office 10 times in the past year, including one phone call.
Bost, however, said the emails were not threatening and didn't raise red flags with his staff.
