President Donald Trump made a fresh appeal Friday for support to arm some teachers to help stem mass shootings targeting schools.

Trump's pitch came during a speech before a friendly conservative crowd at the annual Conservative Political Action Conference (CPAC) meeting near Washington.

Trump spent much of the past week dealing with the aftermath of the tragic high school shooting in Parkland, Florida. Although a new experience for Trump, it is a situation many of his predecessors are all too familiar with.
Former Presidents Bill Clinton, George W. Bush and Barack Obama all faced similar tragedies while in office. They also dealt with political pressures in the aftermath demanding action.

Trump is also beginning to see why presidents are often frustrated when they try to bridge what pollsters and political pundits often refer to as the great divide over guns in the United States.

In the aftermath of the massacre at Columbine High School in Colorado in 1999, President Clinton sought to calm the nation. "We must do more to reach out to our children and teach them to express their anger and to resolve their conflicts with words, not weapons," he said.

In 2007, it was left to President Bush to lead the grieving at Virginia Tech after a gunman killed 32 people before committing suicide. "May God bless and keep the souls of the lost, and may his love touch all of those who suffer in grief," he said at an on campus memorial service.

And in 2012, an emotional President Obama wiped away a tear as he addressed the nation in the wake of the massacre of grade-school students in Newtown, Connecticut. "We've endured too many of these tragedies in the last few years. The majority of those who died today were children, beautiful little kids between the ages of five and 10 years old," he said.
Trump has expressed sympathy for the victims and families in the shooting at Marjory Stoneman Douglas High School in Parkland, Florida. But he has also been forceful in pushing for solutions, including the controversial idea of arming some teachers.
