Senate Minority Leader Chuck Schumer, D-N.Y., said Tuesday President Trump’s indecision on guns after the school shooting in Parkland, Fla., is making the road toward passing any gun control legislation more difficult.

Schumer told reporters Tuesday that, while he is pleased the president has spoken out on the issue, lawmakers are not entirely sure what legislation Trump will or will not sign as proposals are floated on Capitol Hill. He has pointed to their multiple negotiations in recent months, particularly on immigration and the Dreamers, as his reason for pause.
