Premier Shawn Graham and federal Revenue Minister Keith Ashfield showed no signs of lingering frustration at a Friday morning event only days after accusations of political interference were being hurled between Fredericton and Ottawa.

The Liberal premier and federal Conservative cabinet minister officially opened an expanded addiction-treatment facility for youth in Cassidy Lake in southern New Brunswick.

Earlier this week, Graham accused Ashfield of holding up federal funding for projects in the province in order to help the provincial Progressive Conservatives win the election in September, a charge that Ashfield denied.

Graham and Ashfield refused to back away from their positions on Friday but they were diplomatic when they met reporters.

Graham said he was optimistic any federal-provincial funding disagreements will soon be resolved.

For instance, the New Brunswick premier said he hopes a funding deal to repair the Harbour Bridge in Saint John could be reached by a June 30 deadline.

Tory MP Greg Thompson, a former federal cabinet minister who is retiring from politics, said Ashfield told him they were stalling funding projects in New Brunswick until after the Sept. 27 election.

Thompson said he had an email sent from Ashfield's chief of staff that indicated that projects were being put on hold until after the vote.

Ashfield repeated his assertion on Friday that an email supposedly showing political interference has been taken out of context.

Ashfield said on Friday that a series of upcoming announcements shows there is no delay in getting New Brunswick projects approved.

Graham, however, pointed out Friday's announcement had been approved by Thompson months ago when he was the province's senior federal cabinet minister.
