Ground Zero Cross to be permanent artifact at 9/11 Museum

One of those artifacts, a cross-shaped steel beam found amid the rubble, has stirred controversy in recent days. American Atheists, a nonprofit group, filed a lawsuit arguing that the cross, which became a symbol of hope to many in the days after the attacks, violated the Constitution because it is a religious symbol and the museum is partly financed by the government.

Mr. Bloomberg, asked about the lawsuit, defended the cross, saying it was a part of history.

“In a museum you want to show things that impacted people’s behavior back then, even if you don’t think it was right,” he said. “Museums are for history.”

He noted that other religious artifacts would be displayed, including a Star of David cut from the steel of the towers, a Jewish prayer shawl and a Bible.

“A lot of people looked to religion for strength after the attack,” he said. “You shouldn’t tell people what religion to practice or whether to practice a religion, but you also shouldn’t prevent people from practicing any religion they want in any ways they want.”
