The suspect supposedly identified himself as a reporter with the David Brock-founded American Bridge, which is "a progressive research and communications organization committed to holding Republicans accountable for their words and actions."

The suspect, whose name has not been released, allegedly "pushed a female Interior Department communications official to the floor, chasing after Zinke," the DCNF notes.

According to Politico, Laura Rigas, Interior's communications director, said she was "greatly alarmed and extremely irate that a female senior member of my DOI Communications team was physically assaulted today by a Democrat staffer from the PAC American Bridge."

Committee spokeswoman Katie Schoettler told the DCNF that the committee was "appalled to hear of the events following yesterday’s hearing where a member of Secretary Zinke’s staff was victim to an assault."

“These actions are reprehensible and have no place in this body. We thank the U.S. Capitol Police for their quick response and professionalism,” Schoettler continued. “The USCP is now handling the matter.”
