MADISON, Wis. -

U.S Rep. Paul Ryan of Janesville called Rep. Eric Cantor a good friend and great public servant the day after Cantor lost a Virginia primary in a stunning upset.

"Right now, I'm just disappointed that my friend lost,” Ryan said. “Eric has worked hard on behalf of his constituents, and he's been a leader here in the House.”

Cantor is expected to step aside as majority leader on July 31 after losing Tuesday's primary to college professor and political novice Dave Brat, who triumphed in the Richmond-area district with tea party support.

Most Republicans viewed Cantor, 51, as the most conservative member in the House leadership and a likely successor to Speaker John Boehner of Ohio.

The decision sets up a leadership scramble among Republicans in the House.

A source close to Ryan told News 3 Ryan remains focused on chairing the House Budget Committee and representing the First District of Wisconsin and has no intention of running for a House leadership position.
