Preliminary tests are negative on a white powder that was mailed to several New Jersey hotels near MetLife Stadium, the site of Sunday's Super Bowl.

One envelope was received at an Econo Lodge in Carlstadt, while others turned up at two other hotels nearby. According to Fox News' Rick Leventhal, authorities intercepted a mail truck that had additional envelopes going to two other hotels in the area.

Also, the NYPD says a substance mailed to the office of former NYC Mayor Rudy Giuliani was found to be non-toxic.
