People wave and take pictures of Pope Francis as he leaves Benito Juarez International Airport upon arrival to Ciudad Juarez, Mexico, Wednesday, Feb. 17, 2016. The pontiff is scheduled to wrap up his trip to Mexico on Wednesday with a visit in a Ciudad Juarez prison, just days after a riot in another lockup killed 49 inmates, and a stop at the Texas border when immigration is a hot issue for the U.S. presidential campaign.
