BOSTON – Taxpayer funding to build an institute honoring the late Sen. Edward Kennedy is rising, leading one critic to say it should be financed privately.

Federal earmarks of about $38 million have been made available for the facility, which is to be located adjacent to the John F. Kennedy Presidential Library at Columbia Point.

Sen. John Kerry and Rep. Edward J. Markey have recently tapped $30 million more in the next budget. They say the center could draw tourists.

David E. Williams of Citizens Against Government Waste says the Kennedy family should finance the project privately.

The head of the planned institute said most of the funds would come from private donors.
