Former Vice President Joe Biden said he is committed to choosing a woman as his running mate if he is the Democratic nominee at CNN's 11th Democratic debate on Sunday night.

"If I'm elected president, my cabinet - my administration - will look like the country, and I commit that I will in fact appoint a woman to be vice president," Biden said during an unusual debate that did not have a studio audience because of precautions around the coronavirus pandemic. "There are a number of women who are qualified to be president tomorrow. I would pick a woman to be my vice president."

"Democratic victory in 2020 will depend on record-breaking participation by women," the groups wrote in a letter to the DNC. "Women are the backbone of the Democratic party. Women are a majority of Democratic voters, volunteers, and donors."

Sanders, when asked the running-mate question, said he would "in all likelihood" pick a woman as vice president, but reminded everyone that he believes ideology is more important than representation. "For me, it's not just nominating a woman. It is making sure that we have a progressive woman, and there are progressive women out there," he said.
