Vivek Ramaswamy Sinks to Fat-Shaming Chris Christie in GOP Debate

Republican presidential candidate Vivek Ramaswamy took a low blow at former NJ Gov. Chris Christie in the latest Republican debate, essentially telling him to get out of the race and go stuff his face.

Ramaswamy fired off the remark Wednesday night in Tuscaloosa, Alabama ... claiming Christie's only experience on the topic of foreign policy was shutting down the George Washington Bridge -- an infamous moment during his time as Governor.

That woulda been politics as usual, but then Ramaswamy took it to fat-shaming -- he added, "Just walk yourself off that stage, enjoy a nice meal, and get the hell out of this race."

The crack garnered some applause, but mostly a whole lotta booing.

His harsh words came after Christie jumped to fellow candidate Nikki Haley's defense -- Ramaswamy accused her of not knowing where specific provinces in Ukraine were if she was given a map.

Christie called her a "smart, accomplished woman," and blasted Ramaswamy for being, in his eyes, "the most obnoxious blowhard in America."

Frontrunner Donald Trump again wasn't in attendance for the 4th debate, but he grabbed plenty of headlines leading up to it.
