Looks like that 400% number came from this:

This week the journalist Ronald Kessler’s new behind-the-scenes account of presidential security, “In the President’s Secret Service,” rose to No. 3 on The Times nonfiction best-seller list. No wonder there’s a lot of interest in the subject. We have no reason to believe that these hugely dedicated agents will fail us this time, even as threats against Obama, according to Kessler, are up 400 percent from those against his White House predecessor.
