Washington (CNN) Sen. Amy Klobuchar said she thought she might have gotten hit in the middle of a heated exchange between businessman Tom Steyer and former Vice President Joe Biden during Tuesday's Democratic presidential debate.

"That moment with those two, they were going at it and I stood there," the Minnesota Democrat recalled on Wednesday night during CNN's presidential town hall in South Carolina . "And what was somewhat amusing about it was that Tom Steyer was so heated he was moving into my little area right there, and so I actually thought -- he was flailing his arms -- that I actually might get hit in the process."

"And then I thought, well, if something happens and I fall off my little stool I was standing on because I'm the only one who is truly 5-foot-4 -- despite the fact that the President called Michael Bloomberg 5-foot-4, I'm the only one that can hold that -- and I thought to myself, 'At least Steyer has deep pockets,' " Klobuchar said laughing.

"I'll be in good shape," she added. "I can get something out of this and it will be OK."

The tense moment had come during a contentious debate that saw the Democratic contenders continually take aim at Sen. Bernie Sanders of Vermont, who has solidified his status as the party's front-runner after claiming victory in the Nevada caucuses on Saturday.
