Amid a growing call for action on guns, the White House said Sunday the president will host a "listening session" with students and teachers this week, but offered no details on who would attend or what would be discussed.

On Monday, 17 Washington students plan a "lie-in" by the White House to advocate for tougher gun laws. Students who survived the shooting at Marjory Stoneman Douglas High School in Parkland are planning a march on Washington next month to pressure politicians to take action on gun violence.

Some lawmakers said it would take a powerful movement to motivate Congress.

"I am not optimistic that until there is real action by the American public to demand change in Congress that we're going to see real action to confront gun violence out of this Congress," said Sen. Chris Coons, D-Del., on CBS' "Face the Nation."

Trump was last seen publicly Friday night when he visited the Florida community reeling from the school shooting that left 17 dead. White House aides advised the president against golfing so soon after the tragedy, so Trump spent much of the holiday weekend watching cable television news and grousing to club members and advisers.

Trump met Sunday afternoon with Republican House Speaker Paul Ryan, discussing immigration, taxes, infrastructure and the Florida shooting, the White House said.

Throughout the weekend, the president's mind remained on Russia after an indictment from special counsel Robert Mueller on Friday charged 13 Russians with a plot to interfere in the U.S. presidential election.
