LIVE: Clinton projected to win the Nevada Democratic caucuses

UPDATE: Former Secretary of State Hillary Clinton defeated Sen. Bernie Sanders in the Nevada Democratic caucuses, multiple outlets reported Saturday evening.

NBC, The Associated Press, The New York Times, and Fox News all called the race for Clinton, who quickly thanked her supported on Twitter.

"To everyone who turned out in every corner of Nevada with determination and heart: This is your win. Thank you," she wrote.

Long seen as a key part of her "firewall" against a surge in support for Sanders, the state's notoriously unreliable polls showed a tightening race in recent weeks following Sanders landslide win in the New Hampshire primary.
