Former Secretary of State Hillary Clinton is making news on who she would choose for Vice President, even though she hasn’t officially won the Democratic nomination.

“The most important thing is to pick someone who you have absolute confidence in can be president,” she said on Meet the Press on Sunday. “That’s more important than any characteristic.”

Clinton added that any vice president would have to be a good partner for her, one that she could work with and would help run the entire United States government.

She cited Vice President Joe Biden as someone who had done “very well” for President Barack Obama.

Clinton’s comments will likely anger supporters of Bernie Sanders, especially as she continues to lose states to the Vermont Senator.

Last week, Clinton angered Sanders for essentially declaring victory in the Democratic race.

“I will be the nominee for my party … That is already done, in effect,” she said in an interview on CNN. “There is no way that I won’t be.”

Clinton hinted that her vice president might come from the private sector, suggesting that she would be open to the idea of a businessman to combat Donald Trump’s appeal.

“I think we should look widely and broadly. It’s not just people in elective office. It is successful businesspeople. I am very interested in that,” she told Meet The Press host Chuck Todd.
