In an impromptu hallway conversation with CQ Roll Call on Tuesday, Rep. Tony Cárdenas did not confirm nor deny reports that his district director was subpoenaed by a federal grand jury about using staffers to conduct campaign work.

“I don’t know more than what you guys have been trying to say in the press,” Cárdenas said during the two-minute conversation.

When CQ Roll Call posited that Cárdenas must know why his staffer was subpoenaed, Cárdenas said he didn’t.

“No. I am not able to confirm any of that,” he said.
