"It's not a Muslim ban," Trump told reporters in the Oval Office after he signed three new directives.

The order, handed down Friday evening, sowed chaos as government agencies scrambled to implement the broad new policy.

But Trump insisted his administration was "totally prepared" to carry out the refugee and travel ban, which affects more than 100 million people around the world.

"It's working out very nicely," he said. "You see it at the airports, you see it all over."
