The soon-to-open National September 11 Memorial Museum will include reflections from Democratic U.S. Rep. Keith Ellison, the first Muslim elected to Congress, on the effects of the attacks on America, the museum said.

Ellison will appear in the "Reflecting on 9/11" exhibition, which features video segments from elected officials and family members affected by the Sept. 11 terrorism attacks.

The exhibit will also include recording booths, where visitors will record their reflections about the attacks. Over time, their thoughts will be added to the main presentation.

The museum is set to open May 21 at the World Trade Center site in New York City.

With the exhibit still under construction, museum officials don't have a breakdown of Ellison's exact statements, said communications manager Anthony Guido.
