The 56-year-old, told media interviewers she complained at the time about sexual harassment, though not sexual assault, to three of Biden's Senate aides.
The woman who alleges presumptive Democratic presidential nominee Joe Biden sexually assaulted her in 1993 said in a video interview on Thursday that he should withdraw from the White House race, saying Thursday she'd take a polygraph about the alleged encounter if he would.
Tara Reade's comments in an television interview came six days after Biden said in his first public remarks about the alleged incident that it "never happened."
In an interview, Tara Reade urged Biden to "please step forward and be held accountable".
She added: "You should not be running on character for the president of the United States."
The 56-year-old has claimed Biden sexually assaulted her in 1993, when she was working as a staffer in his Senate office.
The former Senate staffer added that she has been hacked and received a death threat since accusing Biden of sexual assault.
Responding to Reade's latest interview, Biden's deputy campaign manager, Kate Bedingfield, said on Thursday that "more and more inconsistencies keep emerging" in Reade's account.
The statement did not address Reade's call for Biden to drop out of the race.
Reade told media interviewers she complained at the time about sexual harassment, though not sexual assault, to three of Biden's Senate aides.
A 1996 court document indicated that Reade had told her ex-husband she was sexually harassed while working for Joe Biden.
The Biden campaign released a statement from one, Marianne Baker, who said she never received any report of inappropriate behavior in nearly 20 years of working for Biden.
Biden last week asked the Secretary of the Senate to make public any records containing a complaint or other documents relating to Reade's allegation, if they exist. The Senate denied the request because of confidentiality requirements.
Some prominent Democratic women including US House of Representatives Speaker Nancy Pelosi and US Senator and former presidential rival Elizabeth Warren have defended Biden, who was President Barack Obama’s vice president.
