Comedian Jon Stewart has joined the board of the foundation in charge of building the September 11 memorial in New York.
Mayor Bloomberg, chairman of the National September 11 Memorial & Museum, appointed "The Daily Show" host to its board of directors. Other members include victims' family members and community leaders.
Stewart has used his Comedy Central show to draw attention to the Zadroga health bill, which would provide funds to treat workers who became ill from dust at the World Trade Center. He interviewed first responders who would benefit from the legislation and mocked those who opposed it.
Stewart, who lives in Tribeca, spoke at the annual benefit for the memorial in September. The memorial is set to open to the public on September 11, 2011.
