(CNN) House Speaker Nancy Pelosi said Friday she was forced to nix her Afghanistan trip after President Donald Trump barred her from using a military aircraft and she was told by the State Department diplomatic security that it was too dangerous to fly there commercially.

"We weren't going to go because we had a report from Afghanistan that the President outing our trip had made the scene on the ground much more dangerous because it's just a signal to the bad actors," Pelosi told reporters at the Capitol.

"You never give advance notice of going into a battle area. You just never do. Perhaps the President's inexperience didn't help him understand that protocol. The people around him, though, should have known that, because that's very dangerous," she said.

The speaker also said the President's announcement of the trip had endangered members of Congress and American troops, and that she was just relaying what the State Department told her office.

"This is a fact. It's not even an opinion," she said.
