(CNN) Democratic Sen. Mazie Hirono called Republican Sen. Susan Collins' comments on Christine Blasey Ford "insulting" to Ford and other victims of sexual assault.

"She said that Dr. Ford thinks that she was assaulted, which is even more insulting than saying that she gave a very credible account ..." Hirono said. "What is that? Is [Ford] mistaken?"

Ford alleged that newly confirmed Supreme Court Justice Brett Kavanaugh sexually assaulted her while the two were at a party in high school, and other accusers soon came forward. Kavanaugh has denied all the allegations.

The Hawaii Democrat criticized Collins for her views in light of the Maine Republican's meetings with sexual assault survivors.

"She herself said she spoke to so many survivors from her state and elsewhere," Hirono said. "They kept all these painful, traumatic accounts to themselves. This is what happens with sexual assault survivors, that they do not come forward."
