Firebrand Senator and potential 2020 presidential candidate Elizabeth Warren was stunned during a live debate Tuesday night, when she was apparently unaware of an ethics complaint filed against the legislator for her fundraising efforts during Judge Kavanaugh’s confirmation hearings.

Warren was debating her GOP opponent Geoff Diehl when he blindsided the lawmaker with a recently filed complaint, saying she “was fundraising illegally.”

“Senator Warren was fundraising illegally using the vote on Justice Kavanaugh, the confirmation vote, to try to raise money for her campaigns,” Diehl said.

“Actually, I don’t know,” said Warren to audible gasps from the audience.

“Then, then I will, I will check into it,” Warren said, “but I don’t know.”
