The statement from Cochran's office: "Sen. Cochran will not be co-hosting the event." That makes five members of Congress who've yanked their support for the conference in less than 12 hours. When was the last time a conference had that kind of problem? How many more will drop out tomorrow? What kind of operation is J Street running that they have this many people claiming their names were being used without their consent? And for the members of Congress who remain on that list -- what kind of message are they trying to send by endorsing a conference that will feature a speaker who blamed Israel for 9/11, that will agitate against the very Iran sanctions legislation most of them voted for, and that will be a forum for Israel-bashers and Hamas sympathizers to rub elbows?
