Trump's pick to head U.S. intelligence has broken with its assessments several times since the Sept. 11, 2001, terrorist attacks.

Nominee Tulsi Gabbard was rigorously questioned by Senator Mark Kelly over her past skepticism of U.S. intelligence on Syria.

Gabbard was questioned by Republicans and Democrats alike on her views of Snowden and whether she believes he was a traitor. She declined to say she believed he was a traitor, repeating that she felt he had broken the law and reiterating a point that she has made in the past, that he exposed practices that have resulted in the reform of 702.
