President Trump announced Thursday he is planning a trip to Parkland, Fla., the site of Wednesday’s school shooting that left 17 dead and more than a dozen injured.

“I’m making plans to visit Parkland to meet with families and local officials, and to continue coordinating the federal response,” he said in a brief speech from the White House.

Trump also called for national unity, and said the country must come together to protect children in schools and help people with mental illnesses.

“Our entire nation, with one heavy heart, is praying for the victims and their families,” Trump said.
