WASHINGTON – President Trump has finalized his plan to impose restrictions on guns and improve school safety that will be released Sunday evening.

Among the quickest actions Trump expects completed is a ban on the sale of bump stocks by expanding the definition of illegal machine guns to include the devices.

“Within in a couple weeks, we could have a rule implemented,” deputy White House press secretary Raj Shah told the Post Sunday.

The plan will include recommendations for states, Congress and for administrative action. In the weeks since the Parkland high school shooting that killed 17 students and staff, Trump has expressed support for arming certain teachers, raising the age to 21 to buy semi-automatic weapons and improving background checks.

He’s expected to urge state action — rather than pass federal laws — to increase the age limit on certain gun purchases and also encourage states to allow trained school staff to carry concealed weapons, according to the Wall Street Journal.

Trump has already said he supports a narrow bill, known as Fix NICS, to strengthen the records in the federal background check system by improving state and military compliance to turn over convictions.

But there’s bipartisan support for broader reforms to make gun background checks universal to gun shows and online sales as well as a measure to ban people on the terrorist watch list from buying guns. Both would need Trump’s blessing for a congressional vote, though those proposals don’t appear to be part of the White House plan.

Trump is expected to back a bill slated for passage in the House this week called the STOP School Violence Act, which would provide $50 million a year in school grants to improve violence prevention training and crisis invention programs.

The White House also wants a task force to study gun violence and schools safety issues and make further policy recommendations, Shah said.

Students from Marjory Stoneman Douglas High School in Florida have demanded action since the Valentine’s Day massacre. Their activism helped spur Florida to pass new gun laws, including raising the age from 18 to 21 on buying firearms.

The National Rifle Association immediately filed suit against the new gun restrictions in Florida.
