House Majority Leader Eric Cantor has been defeated by a tea party-backed challenger in the Republican primary.
Economics professor Dave Brat won a stunning upset victory against Cantor on Tuesday in the 7th District Republican primary contest, which is in the Richmond area.
Cantor is the second-most powerful member of the U.S. House and was seen by some as a possible successor to the House speaker.
His loss to a political novice with little money marks a huge victory for the tea party movement, which supported Cantor just a few years ago.
Brat had been a thorn in Cantor's side on the campaign, casting the congressman as a Washington insider who isn't conservative enough. Last month, a feisty crowd of Brat supporters booed Cantor in front of his family at a local party convention.
