Security around the White House is always ramped up a notch or two or three whenever the prime minister of Israel comes to town, and such was the case today at the White House. At 2:50 this afternoon a secret service uniformed officer came to our temporary office at 12 Jackson Place and told us we had to evacuate. And, is often the case, they didn't tell us why, except they were examining a suspicious vehicle. So we put everything down, quickly strode down two flights of stairs and out in the 90 degree plus heat. Downtown traffic around the White house ground to a halt, and muttering members of the White House press corps tried to get some information to no avail for more than an hour and 25 minutes. Only then did we got a call back from the Secret Service with an explanation. The suspicious vehicle was a mini-van belonging to none other than the Israeli delegation. As it turned to enter the White House complex a bomb sniffing dog "hit" on it. Nobody is saying why, but the probable explanation is that at one point the van carried something that probably that contained chemical used in explosives. The "incident" was over at 4:15. Traffic returned to normal and we trudged back to our workspace.
