The controversial idea to put weapons in schools, which has drawn little support from educators, is part of a "pragmatic plan to dramatically increase school safety and to take steps to do so right away", Education Secretary Betsy DeVos said in a conference call with reporters. The commission does not have a set timeline of when it will report its findings, although an official said it would be within one year.
"We're going to be very fair and very flexible, but we're going to be protecting the American worker", the president said.
"We can't just keep setting up blue ribbon committees with your wife and your wife and your husband, and they meet and they have a meal and they talk", Trump told a campaign rally in Pennsylvania.
Tapping into Justice Department resources and finances, the government will help states partner with law enforcement agencies to train school personnel who volunteer, the White House explained.
