As rioters pounded on doors and smashed through glass windows at the U.S. Capitol last week, Rep. Alexandria Ocasio-Cortez (D-N.Y.) says she worried that her own colleagues in Congress might divulge her location to the mob outside, putting her at risk for kidnapping or worse.

In the midst of the chaos, the lawmaker revealed on Tuesday night, she also experienced “a pretty traumatizing event” that left her fearing for her life.

“I can tell you that I had a very close encounter where I thought I was going to die,” she said, noting that she couldn’t get into specifics for security reasons. “I did not know if I was going to make it to the end of that day alive.”
