President Donald Trump speaks in the Oval Office of the White House in Washington, Tuesday, March 21, 2017, after signing a bill to increase NASA's budget to $19.5 billion and direct the agency to focus human exploration of deep space and Mars. Earlier in the day, Trump singled out U.S. Rep. Mark Meadows, R-N.C., over his opposition to a GOP bill that would repeal and replace Obamacare. Meadows has said he’s worried the proposal wouldn’t do enough to lower insurance premiums. Evan Vucci AP
