In a Feb. 15, 2018, file photo, President Donald Trump speaks in the Diplomatic Room at the White House, in Washington, about the shooting in Parkland, Fla. When shots rang out at a high school in Parkland, Florida last year, leaving 17 people dead, Trump quickly turned his thoughts to the need for more mental institutions. When back-to-back mass shootings in Dayton, Ohio, and El Paso, Texas, jolted the nation earlier this month, Trump again raised the need for “building new facilities” for the mentally ill as a way to prevent mass shootings.
