Former Democratic congressman, Artur Davis, will address the Republican National Convention in Tampa.
Davis served as Barack Obama's Alabama campaign chairman four years ago and gave the seconding speech for Obama's nomination at the Democratic National Convention.
But the Republican National Convention announced Thursday that Davis will speak later this month at the GOP convention in Tampa, Fla., to support Mitt Romney.
Davis lost Alabama's Democratic primary for governor in 2010. Then he moved to Virginia and later switched parties.
Davis said Thursday the talk by Obama that inspired people four years ago has not been backed up by actions to increase jobs.
Instead, he said it has resulted in job-killing mandates and trillion dollar deficits.
