"I shouldn't have said what I said," Biden said in an interview with Pod Save America on March 28.
"Now, the idea that I would actually physically get in a contest with a president of the United States or anybody else now is not what I said," Biden told the podcast. "It is not what this was about, but I should have just left it alone."
"A guy who ended up becoming our national leader said, ‘I can grab a woman anywhere and she likes it.' They asked me if I'd like to debate this gentleman, and I said no. I said, ‘If we were in high school, I'd take him behind the gym and beat the hell out of him,'" Biden proclaimed during the rally.
Trump reacted to Biden's speech on Twitter, saying Biden is trying to act like a "tough guy."
This battle of the titans might be closer than either of the potential pugilists will admit: a Public Policy Polling survey found that 37 percent of voters thought 75-year old Biden would triumph over 71-year old Trump in fisticuffs; 32 percent favored Trump in such a matchip and 30 percent had no opinion.
