David French of National Review and Greg Corombos of Radio America applaud President Trump for hosting a dignified event on school shootings that included a wide variety of opinions from many anguished families.  They also slam CNN for letting it’s town hall on guns turn into an endless onslaught against Marco Rubio, because he will not support an “assault weapons” ban, with one student even telling Rubio he feels like he’s looking at the shooter or down the barrel of an AR-15 when he sees Rubio.  And they shake their heads at the news “Jeopardy!” host Alex Trebek is scheduled to moderate a debate later this year in the Pennsylvania governor’s race.
