So according to the Star:
Just before a parliamentary delegation left for Beirut, Prime Minister Stephen Harper's office decided that no Conservative would be part of the trip.
Tory MP Dean Del Mastro (Peterborough) pulled out, telling organizers the Prime Minister's Office had security concerns.
Gee Steve, do ya think it has something to do with all your "Measured Response" crap? You think the people over there might, just might, have a problem with that.
Don't worry, they will be too busy rebuilding thier homes to give you that much trouble.
