Rack up another top endorsement for presidential candidate Newt Gingrich.

This time, it comes from decorated war hero who formerly supported Texas Gov. Rick Perry in his concurrent presidential bid. 

See who else has withdrawn support from Perry, but has backed another candidate.

Maj. Gen. James Livingston endorsed Gingrich Wednesday. 

"I appreciate Governor Perry's efforts, and adore him and his wife Anita. But I have come to the conclusion that Republicans need to get behind a conservative candidate who is developing the momentum needed to win in South Carolina and beyond," Livingston said in a release.

"I believe Newt Gingrich is the firewall Republicans can rely on to block a liberal agenda that will destroy America’s position of strength in the world. It is imperative for Republicans in South Carolina and beyond to rally behind a conservative candidate who is capable of winning both the SCGOP and the national Republican primaries."

On Monday, both the Gingrich and Livingston addressed those gathered at the S.C. Tea Party Convention in Myrtle Beach. There, he said that all candidates "have warts" under close examination. 

Livingston will introduce Gingrich at a special veterans town hall event at 8 p.m. Friday at Patriots Point in Mount Pleasant.
