Gov. Chris Christie on Sunday said Donald Trump's claim that "thousands and thousands of people" cheered in Jersey City as the Twin Towers fell on 9/11 is not what he remembers about that day.<br />"I don't recall that.<br />I don't," Christie - who is running against Trump for the 2016 Republican presidential nomination - told reporters while on the campaign trail in New Hampshire.<br />Christie often recalls for people at his campaign stops how he feared for his wife's safety on 9/11 when he lost contact with her for about five hours during the terrorist attacks.<br />The governor offered his response to the billionaire businessman's recent comments at a rally Saturday night in Birmingham, Ala.
