AP Kansas senators say they're encouraged by President Obama's budget proposal that includes funding for a biodefense lab in Manhattan. But they acknowledge there's still work to do in Congress to make sure the money comes through. Republicans Jerrry Moran and Pat Roberts said Wednesday's news that Obama's budget includes $714 million for construction of the National Bio and Agro-Defense Facility is good news for the Kansas economy. They say the lab is vital to keeping Americans safe from biological threats. But Roberts says work remains to convince Congress to follow through on the proposal. Efforts to fund the Kansas site have met resistance from New York politicians, who've been battling to keep the nation's current facility in their home state.
