In recent months, former Vice President Joe Biden has faced scrutiny over his interactions with women, as well as his refusal to apologize for his controversial behavior.

Eight women have accused Biden of touching them inappropriately or invading their personal space in ways that made them feel uncomfortable. None of them said Biden's behavior amounted to sexual harassment or assault.

Biden released a two-minute video after the initial allegations came out, but he was criticized for giving what critics deemed a “non-apology apology,” in which he said he would try to do better moving forward. He later said he's “not sorry for anything that I've ever done.”

The Delaware Democrat was further criticized for repeatedly making light of the allegations, and for commenting on the physical appearance of young girls he's met on the 2020 campaign trail in recent weeks.
