Today, the beam signed by President Obama and First Lady Michelle Obama during their visit to the World Trade Center site on June 14th was installed in One World Trade Center – it’s among the final beams added to the 104-story building.
During their visit earlier this summer, the President toured the rising skyscraper, greeted construction workers and signed the steel beam. In red marker, the President wrote: "We remember. We rebuild. We come back stronger!"
