PRESIDENT Obama has (finally) issued an invitation to Taoiseach Brian Cowen for the annual White House bash on St Patrick’s Day. But will any leaders north of the border be attending the jolly? Only one other foreign leader seems to be in Obama’s White House diary for March, and there’s no information on OFMDFM’s website at the time of writing. McGuinness and Donaldson were in Washington last year, but will the Assembly be represented in the new president’s first year? Probably just the new administration’s teething problems, but you never know. It’s certainly not the kind of thing you’d expect Marty and Peter to keep under their hats.
