Pelosi defends Biden amid Tara Reade allegations

“The happiest day for me this week was to support Joe Biden for president of the United States. He is a person of great integrity, of great concern for the American people...I believe that he will be a great president of the United States. He is a personification of hope and optimism and authenticity for our country, a person of great values," Pelosi said.

Presumptive U.S. Democratic presidential nominee Joe Biden is facing growing calls from within and outside his party to respond to a former aide's allegation that he sexually assaulted her nearly 30 years ago, an assertion Biden's campaign has denied.

Tara Reade, who worked as a staff assistant in Biden's U.S. Senate office from December 1992 to August 1993, has accused Biden of pinning her against a wall in 1993 and reaching under her shirt and her skirt.
