James Whittemore pleaded not guilty Thursday to charges including burglary.
The 22-year-old is accused of using a metal pole to break several of the Ed Sullivan Theater's glass doors and damaging items inside early on July 10. The set of Letterman's "Late Show" wasn't harmed.
A court document filed Thursday says Whittemore told police he had a fuzzy memory of the last of several bars he visited and then he remembered being on the Manhattan theater's floor. The document says he called the incident "embarrassing."
