Student survivors of the deadly Florida school shooting who hope to become the face of a revived gun control movement are on a potential collision course with U.S. President Donald Trump.

Several of the students have criticized the president, whose election was strongly supported by the National Rifle Association and who ran on a platform opposing gun control. Trump spent the weekend at his estate in South Florida, only an hour's drive from Marjory Stoneman Douglas High School where 17 people were fatally shot last week. His only mentions of the massacre came in tweets Saturday contending that the FBI was too focused on the Russia investigation to respond to warnings about the alleged shooter and mocking Democrats for failing to pass gun control.

"You're the president. You're supposed to bring this nation together, not divide us," said David Hogg, a 17-year-old student at the Parkland school, speaking on NBC's "Meet the Press."
