It's true—the young woman who was seen hiding under a sheet as she was carried out of a police station is the niece of Vice President Joe Biden.

Twenty-six-year-old art dealer Caroline Biden was busted reportedly after getting into an argument with her roommate at their swanky New York apartment.

When police arrived to sort out the dispute, Biden allegedly slapped one cop and took a swing at a female officer.

Caroline Biden is the daughter of the vice president's younger brother. Biden's niece was given a summons for resisting arrest.
