Homan confirms 'criminal' investigation involving Ilhan Omar, says he knows 'things are going on’

White House border czar Tom Homan confirmed on "The Sunday Briefing" that the Department of Homeland Security is looking into allegations involving Rep. Ilhan Omar, D-Minn., but would not disclose details about what he described as an "ongoing criminal investigation."

Pressed on whether the federal government has evidence that Omar committed immigration or naturalization fraud, Homan declined to comment.

"I know things are going on, but I can't give specifics of what's happening," Homan said.
