Atheists are trying to oust the “Miracle Cross” from the 9/11 museum arguing that its inclusion would violate the Constitution’s separation of church and state.

But Eric Baxster of the Becket Fund for Religious Liberty told MyFoxNY that the cross is part of the story of 9/11 and that museums don’t censor history.

“They tell history as it happened,” Baxster said.

The 17-foot cross-shaped beam was discovered in the devastation at Ground Zero and became a symbol of comfort and hope after the horrific terrorist attack.
