Lindsay Lohan tussles with congressional staffer in Manhattan hotel room over cellphone photos, tells cops he choked her

It’s unclear if she already knew LaBella, who works for Republican Rep. John Shimkus of Illinois and is the nephew of comedian Heather McDonald.

Cops say Lohan took Christian LaBella’s cellphone so she could delete pictures of her partying — and he got physical with her trying to get it back.

After Lohan called the cops, LaBella was initially charged with misdemeanor assault for Sunday’s blowup at the W Hotel Union Square.

But law enforcement sources said the assault rap will be dropped — and LaBella, 25, and Lohan, 26, will both be hit with low-level harassment violations.

It would be Lohan’s second legal scrape in as many weeks, coming on the heels of her arrest for leaving the scene of a minor car accident.
