(CNN) – A Georgia state lawmaker who had been backing Newt Gingrich for the Republican presidential nomination will announce Tuesday that he's now supporting Mitt Romney.
According to the Romney campaign, Georgia State Rep. David Casas will hold a news conference Tuesday afternoon to announce he is no longer backing the former House speaker, who represented Georgia's sixth congressional district for two decades, and instead will endorse the former Massachusetts governor.

"I am proud to endorse Mitt Romney," Casas will say in a Romney campaign release to be sent out later Tuesday. "Over the last few weeks, I have had a serious change of heart. While I initially supported Speaker Gingrich, his continued attacks upon the free enterprise system that has made our country great are particularly something I will not stand for. I look forward to joining the team and urge my fellow Georgians in supporting the clear conservative that will fight for the America we love, Mitt Romney."
"I'm happy to have David's support. David shares my vision of promoting conservative economic policies to create jobs and get our country back on track. I look forward to sharing this message to all Georgians in the months to come, with his help," Romney will say.
Georgia is one of the ten states holding their primaries on Super Tuesday, March 6.
CNN has reached out to the Gingrich campaign for reaction.
