Clooney, mayor to help open 1 World Trade Center observatory

NEW YORK (AP) — New York City Mayor Bill de Blasio, George Clooney and TV news host Anderson Cooper are helping to open the new observatory at One World Trade Center.

De Blasio, Clooney and Cooper are scheduled to be on "CBS This Morning" on Wednesday as the show offers a look at the 102nd-floor space, which opens to the public May 29.

The show will be hosted by Charlie Rose, Gayle King and Norah O'Donnell.

The 104-story skyscraper is the tallest in the United States. It's 1,776 feet (541 meters) tall, the same number as the year of the U.S. founding. It opened late last year.

"CBS This Morning" executive producer Chris Licht says the observatory "is a true symbol of how far New York City has come since Sept. 11."
