Just don’t call them right-wing extremists.

Nearly seven months after Barack Obama was sworn-in to office, a recently published book claims that the US president receives 30 death threats every day.

Author of In the President’s Secret Service Ronald Kessler claims that despite a 400 percent rise in the number of death threats from the 3,000 annually under Bush, Obama’s Secrete Service security team remains over-stretched and under-resourced.

"We have half the number of agents we need, but requests for more agents have fallen on deaf ears at headquarters," a Secret Service agent told Kessler.
