Attorney Ben Quayle (R) will formally enter the race for Rep. John Shadegg's (R-Ariz.) seat on Wednesday.

"I want to go to Washington to stop the expansion of Government into our everyday lives," Quayle said in a statement. "It's time for the next generation to start cleaning up the mess created by the establishment in Washington."

Quayle, who billed himself as a "fourth generation Arizonan," is the son of former Vice President Dan Quayle. He'll join an already crowded GOP primary field.

The primary is August 24.
