Pals say the pressure of being Vice President Joe Biden’s niece made her a “hot mess” – but Caroline Biden apparently had no trouble using her status to try and pull rank on cops, The Post has learned

“I shouldn’t be handcuffed! You don’t know who you’re doing this to,” Caroline Biden barked at police, according to court documents.

Cops arrested Biden at her then luxury rental apartment in Tribeca Sept. 17 after she allegedly went berserk in a door-pounding, screaming confrontation with her roommate over unpaid rent.

After swinging at a female officer then slapping another, cops cuffed her and took her to the station house.

The unstable 26-year-old rambled for nearly two hours, snootily trying to get cops to make the connection between her name and that of her powerful uncle, court papers show.

“My name can’t be on it,” Biden bossily demanded, referring to police paperwork. “I know my rights, I studied law.”

When cops tried to search the Georgetown University grad’s purse she snapped, “I have secret service stuff in there.”

Biden continually referenced her connection to her uncle, despite having complained to friends about how much she hated the pressure of being the VP’s niece, according to socialite and pal Paul Johnson Calderon.

She at one point asked to use the bathroom and when her cell door was opened she announced she was leaving, according to the criminal complaint.

The prima donna, who wasn’t cuffed, tried to slide past an officer who blocked her.

“Don’t touch me,” she squealed, trying to push the cop out of the way. When the officer tried to deposit her back into the cell, she desperately clung to a doorframe to prevent it.

Some cops questioned whether the young woman’s erratic behavior and incessant gabbing might be caused by medication, a source added.

A friend of Biden’s previously told the Post she’d struggled with alcohol and pill addiction and even did a stint in rehab.

In a last ditch effort to escape police custody, Biden appealed to the next best thing to her big shot uncle. “I need to call my father,” she said, referring to her financier dad James Biden Sr.

She’s charged with obstruction of government administration, resisting arrest and harassment.

The blue-eyed Biden sported a mysterious black eye at her appearance Tuesday in Manhattan Criminal Court.
