President Donald Trump never seems to miss an opportunity to take a deeply upsetting national tragedy and somehow make it even worse. From his determination to equivocate after the death of Charlottesville protester Heather Heyer to his latest tone-deaf debacle -- the jaunty "thumbs up" gesture the president flashed when posing for a photo with first responders to Wednesday's massacre at Marjory Stoneman Douglas High School in Parkland, FL.

The Trumps sped through their hospital visit and the president's hasty press conference at the Broward County Sheriff's Office before the motorcade swept off into the night and deposited the chief executive and his spouse at a Studio 54-themed "disco party" at Mar-a-Lago.

Much of the nation recoiled from Trump's show of insensitivity.
