Invasion: The White House is crawling with flies

White House officials say that strenuous debugging measures have been undertaken in recent weeks: Anti-insect lights have been installed in the National Security Council suite and the lower press office. Staff members have been issued fly swatters, and one, Brian Mosteller, stood at the ready during Mr. Obama’s television interviews on Tuesday (a lot of good he did). Some staff members have requested chemical intervention but have been denied.

It’s not clear why there has been so much buzz in the Obama White House. The chief of staff, Rahm Emanuel, who swatted at a fly in a recent interview, has blamed the opening of vents in the West Wing for the infestation, while Mr. Obama’s senior adviser, David Axelrod, has blamed careless staff members who forgot to close unscreened windows, an official said.
