Senators questioned ex-Trump national security adviser Michael Waltz at confirmation hearing about a Signal chat that contained sensitive information.

Waltz is a former Green Beret and Florida representative who resigned from Congress to join the Trump administration. He served as national security adviser for roughly three months. Trump reshuffled his team and named Secretary of State Marco Rubio acting national security adviser on May 1.

Waltz repeated past denials that he did not commit any wrongdoing when he inadvertently added a journalist to a Signal app group chat earlier this year.
