Local law enforcement agencies across the U.S. said Monday night that they were monitoring the situation in Manchester, England, after an explosion ripped through an Ariana Grande concert.

The Department of Homeland Security said there is “no specific credible threat” involving music venues in the United States, but that the public “may experience increased security” around public places and events.

DC WILL NOT ENFORCE SCHOOL CHOICE

Betsy DeVos, the U.S. education secretary, said Monday that although President Trump’s administration will put forward plans of a historic expansion of school choice, the ultimate decision will be left with the states, not Washington.

Politico reported that DeVos made the comments during a speech at an Indianapolis summit hosted by the American Federation for Children.

“When it comes to education, no solution, not even ones we like, should be dictated or run from Washington, D.C.,” she said.
