The Trump administration will continue a ban on all nonessential travel at the U.S. borders with Canada and Mexico through June 22 at the recommendation of the Centers for Disease Control and Prevention, the Department of Homeland Security announced late Tuesday.

The closure at all land ports of entry along the southern and northern borders began in late March and was set to expire this week. On Monday, the CDC ordered the extension of the restrictions on the grounds that allowing nonessential travelers, such as tourists, to enter the United States poses a public safety risk.
