President Obama to visit Ground Zero
The last time Obama visited Ground Zero was as a presidential candidate on Sept. 11, 2008, when 1 World Trade Center -- then commonly known as the Freedom Tower -- was below street level, the memorial plaza had yet to be built, and the entire project was mired in delays and cost overruns.
White House rivals John McCain and Barack Obama visited Ground Zero together on Thursday to commemorate the seventh anniversary of the 9/11 terrorist attacks.
