Rep. Connie Mack IV of Florida, who just this week won the GOP primary for U.S. Senate, was added Thursday to the list of speakers for the Republican National Convention, along with Gov. Bobby Jindal of Louisiana.
"The American people are demanding change, and change is on its way," said Mack, who was elected to the House in 2004 and will face Sen. Bill Nelson in November.
Also addressing the gathering will be Artur Davis, a former congressman who as a Democrat seconded the nomination of Barack Obama.
Davis, a former Alabama congressman, was a Democrat when he seconded the official nomination of Obama at the 2008 Democratic National Convention. He has announced he is joining the Republican Party and supporting Mitt Romney.
In a statement issued by the RNC, Davis said: "We were promised jobs and we got job-killing mandates and regulations. We were promised a fiscally responsible government, and we got trillion dollar deficits, debt that has never been seen, and small business burdened with new taxes and threatened with more taxes."
Jindal led his state's response to the BP oil spill in the Gulf of Mexico in 2010. A Rhodes scholar, he was elected to Congress in 2004 and Louisiana governor in 2007.
Other speakers added to the RNC speakers list Thursday were:
