Businessman David Perdue entered the crowded race for the Republican U.S. Senate nomination in Georgia on Wednesday, releasing a video decrying government overreach and blaming "career politicians" for dysfunction in Washington.

"If we want different results from Washington, we just have to send a different kind of person to Washington,"  said Perdue, the former chief executive of Dollar General and the cousin of former Republican governor Sonny Perdue.

Perdue announced in May that he would form an exploratory committee for the Senate race, so his decision is not a surprise.
