A luxury Manhattan hotel is suing a teenager who it claims has launched a defamation campaign against the establishment after the youth was repeatedly ejected from the hotel bar for attempted underage drinking.

Over the last two months, The Mark Hotel alleges Theodore Weintraub has escalated his behavior, and is now picketing in front of the tony establishment—chanting and wielding signs claiming the hotel “spreads disease,” “Denies the Holocaust,” and other unsavory accusations—which the complaint says are baseless.
