Trump encourages leaders to "defend free speech," claims Christianity is the most persecuted religion

Mr. Trump urged other nations' leaders to celebrate the principles upon which the U.S. was founded nearly 250 years ago, including free speech and religious liberty. The president's comments come days after he said the licenses that enable television networks to air should perhaps be revoked over networks' negative coverage of him.

The president also called Christianity the "most persecuted religion on the planet."

"Together, let us defend free speech and free expression," the president said. "Let us protect religious liberty including for the most persecuted religion on the planet today. It's called Christianity."
