President Barack Obama along with the first lady attended the World Trade Center Memorial on Thursday to sign a steel beam that will be added to the tower being built.
The Obamas were joined by New Jersey Gov. Chris Christie, New York Gov. Andrew Cuomo and Mayor Michael Bloomberg, who also left their signatures.
Before the John-Hancock-ing began, Obama joked to his fellow signers: “Don’t mess it up, everybody!”
Obama admired Cuomo’s penmanship, telling the governor: “That’s a nice signature!”
Obama signed the beam, "We remember. We rebuild. We come back stronger! Barack Obama."
