Trump not retreating on gun control: White House

The White House is defending its newly released proposals on school safety.

“Right now the president's primary focus is on pushing through things that we know have broad bipartisan support or things that we can do from an administrative perspective that we can do immediately,” Sanders said. “But we haven't let go of some of those other things that we're going to continue to review and look at.”

“To no one’s surprise, the president’s words of support for stronger gun safety laws proved to be hollow. Responding to the murder of 17 students and educators by endorsing the gun lobby’s platform is a shameful abdication of the president’s responsibility to lead. Shame on you, Mr. President,” Feinstein said in a statement.

“The president, as you know, doesn't have the ability to just create federal law, and he would need a number of other individuals to come together to help make that happen,” Sanders said. “So what he is pushing forward are things that can immediately be accomplished.”

"He's talking about Congress who actually has the ability to make law, not online polls," Sanders said.

At one point, Sanders was asked outright by a reporter why Trump “chickened out,” but she insisted his ideas in the meeting were still a part of the plan.

“He hasn't backed away from these things at all,” Sanders said. “They're still outlined in the plan. But he can't make them happen with a broad stroke of the pen.”

Late Thursday, the Justice Department announced what it called "new actions" to boost school safety and fight gun violence but what is mostly a renewed push for federal prosecutions and information assistance from state and local law enforcement.

Over the next day or two, Attorney General Sessions will be sending letters to U.S. Attorney offices, other federal and state officials related to the renewed push.

In addition, DOJ announced that $1 million in DOJ funds are being sent to Florida to help local law enforcement repay costs associated with the school massacre in Parkland.
