FILE – In this Feb. 21, 2018, file photo, President Donald Trump, joined by student Carson Abt, right, and Julia Cordover, the student body president at Marjory Stoneman Douglas High School in Parkland, Fla., left, bow their heads during the opening prayer of a listening session with high school students and teachers in the State Dining Room of the White House in Washington. 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.
