Former Speaker of the House Nancy Pelosi, in an interview with Good Morning America anchor George Stephanopoulos on Monday morning, said that she spoke with President Joe Biden ahead of his withdrawal from the 2024 presidential race "asking for a campaign that would win." She also said Biden was "the only person that I spoke to" about Biden possibly withdrawing.

"The only person that I spoke to about this was the president. Other people called me about what their views were about it, and -- but I rarely even returned a call, much less initiated one," Pelosi said.

Later, she added, "I wasn't asking him to step down. I was asking for a campaign that would win, and I wasn't seeing that on the horizon."

Vice President Kamala Harris' choice for her running mate is the "most important" decision she has to make as her campaign gets started, former House Speaker Nancy Pelosi said.

All of her choices for a running mate appear to be good, Pelosi added.

"It's a difficult decision because they are all so great," she told ABC News' George Stephanopoulos on "Good Morning America" on Monday. "It is the most important decision for her to make. Not just about who can help win, but who can help serve and lead and whose confidence she trusts.

Vice President Kamala Harris and her running mate, who is yet to be named, will go on tour, hitting seven battleground states in five days, the Harris campaign said Monday.

The tour will be an effort to "introduce the new Democratic ticket" and "speak directly with voters in their communities and cement the contrast between our ticket and Trump’s,” campaign said.

The tour, which kicks off Tuesday in Philadelphia, Pennsylvania, will feature rallies in cities and stops at college campuses, including HBCUs, union halls, family-owned restaurants and their field offices, the campaign said.

The tour will continue through Eau Claire, Wisconsin; Detroit, Michigan; Durham, North Carolina; Savannah, Georgia; Phoenix, Arizona; and Las Vegas, Nevada, the campaign said.
