Tulsi Gabbard’s support for pardoning Edward Snowden made her one of Donald Trump’s more intriguing picks when she was nominated for director of national intelligence. It has also made her one of his most vulnerable.

Gabbard is set to face pointed questioning from Republican supporters of government spying powers at her confirmation hearing Thursday, and her answers will reveal whether she is willing to flip-flop to secure the post.

Will Gabbard, a former member of Congress who has a long history of switching positions and even parties, change her tune as she already has done on National Security Agency spy powers? The White House did not respond to a request for comment, but senators exiting a closed-door Intelligence Committee hearing Tuesday said to stay tuned.

“We have talked about it privately, and we will certainly talk about it publicly,” said Sen. James Lankford, R-Okla., who has called Snowden a “traitor.”

A Pardon Too Far

Trump has enthusiastically wielded his pardon Sharpie, but one name so far has failed to cross his desk.

For years, supporters of Snowden have urged presidents in both major parties to grant him a pardon in recognition of his consequential leaks in 2013, which revealed both the breadth of NSA spying and the way the government had warped the law to enable it.
