Rep. Nancy Mace, R-S.C., lashed out at Secret Service Director Kimberly Cheatle during her congressional testimony Monday on the July 13 attempt on former President Donald Trump's life.

Mace demanded to know why Cheatle, who has declined to answer many questions due to the ongoing investigation, leaked her opening statement to the press ahead of her appearance before the GOP-led House Oversight Committee.

Cheatle denied knowing how the statement leaked, prompting Mace to exclaim, "That's bullsh*t."

"You're full of sh*t today," Mace later told Cheatle after she refused to answer some of Mace's questions directly, prompting another member of the committee to call for civility in the proceedings.
