Former Vice President Joe Biden says he’s isn’t yet sure if he’ll enter the 2020 presidential race, but if he doesn’t, he claims it won’t be because he’s afraid he’ll lose against President Trump.

“The jury’s still out,” Biden told a crowd at Southern Connecticut State University on Friday, the Hartford Courant reported. “Honest to God, I don’t know.”

If he chooses not to run, he said, it will be because there’s a better candidate or he’s not emotionally ready.

“I have to be able to stand in front of a mirror and look in the mirror and know that if I don’t run, it’s not because I’m afraid of losing, it’s not because I don’t want to take on the responsibility, it’s because there’s somebody better to do it and/or because emotionally I’m not positioned to be all in,” he explained.

Biden decided not to run for president in 2016, citing the death of his son, Beau.

The former vice president and Trump have engaged in a war of words this week over who could beat the other in a fist fight.

Biden initiated the feud during an anti-sexual assault rally Tuesday at the University of Miami. While speaking about a 2005 “Access Hollywood” tape in which Trump was caught on a hot mic talking about inappropriately touching women without their consent, Biden said he’d like to take Trump behind the gym and “beat the hell out of him.”

Trump responded via Twitter, saying Biden “would go down fast and hard, crying all the way.”

Biden walked back his comments Friday in an interview with “Pod Save America.”

“I shouldn’t have said what I said, I shouldn’t have brought it up again because I don’t want to get down in the most pit with this guy,” he said.
