An atheist group is suing to keep a steel cross found in the wreckage of New York City's ground zero from going on display.

The 17-foot-tall beam is set to be displayed in a new ground zero museum. The group American Atheists said displaying the beam would be unconstitutional.

Lawyers from the American Center for Law and Justice criticized the attack on the cross as "absurd."

"The atheists say they are suffering both physical and emotional damages from the existence of the cross. That's right. The mere existence of this memorial has brought on headaches, indigestion, even mental pain," ACLJ Chief Counsel Jay Sekulow said in a statement.

Just as ludicrous, the ACLU said, was the atheist group's suggestion to erect a 17-foot "A" to promote their non-beliefs at the site.

Meanwhile the 9/11 museum stands by their decision to display the cross, saying its job is not to provide equal time for all faiths but to tell the story of 9/11.
