A stunning political upset for the House majority leader Tuesday night was followed by a stunning announcement today.
"Now, while I intend to serve out my term as member of Congress from the seventh district of Virginia, effective July 31, I will be stepping down as majority leader," Eric Cantor said.
Cantor outraised and outspent his virtually unknown Tea Party challenger in the Republican congressional primary, but he lost the nomination anyway.
What went wrong?
What does this mean for the future of the GOP?
OutFront, Republican Congressman Peter King.
