As the White House sought to balance campaign rhetoric with governing, officials appeared willing to extend unemployment benefits. With former Federal Reserve Chairman Alan Greenspan saying he is "pretty sure we've already seen the bottom" of the recession, Obama aides sought to defend the economic stimulus and calm a jittery public. Treasury Secretary Timothy Geithner and National Economic Council Director Larry Summers both sidestepped questions on Obama's intentions about taxes. Geithner said the White House was not ready to rule out a tax hike to lower the federal deficit; Summers said Obama's proposed health care overhaul needs funding from somewhere.
