TOPEKA, Kan. (AP) -- President Barack Obama is recommending no additional funding in the next federal budget for construction of a new biosecurity lab in Kansas.

The budget released Monday raises questions about the future of the National Bio- and Agro-Defense Facility under construction in Manhattan near Kansas State University. The project is estimated to cost $650 million to complete and would replace an aging facility at Plum Island, N.Y.

The administration requested $150 million in the current year, of which only $50 million was appropriated by Congress, which the White House says is insufficient to begin construction.

Obama is asking the Department of Homeland Security to reevaluate the project, while spending $10 million to increase the amount of research being done at Kansas State's Biosecurity Research Institute.
