SAN DIEGO (AP) — U.S. officials are expected to announce new restrictions on the southern border Friday as they try to halt the spread of the coronavirus pandemic. The U.S. and Mexico have been working on plans to halt much of the cross-border travel without disrupting trade. Officials on both sides of the border say the plan is expected to look much like restrictions already announced on all-but-essential travel and trade between the U.S. and Canada. Acting Homeland Security Secretary Chad Wolf says, “We want to make sure that cargo continues, trade continues, heath care workers continue to be able to traverse that border. But tourism, some recreational activities and other things” need to stop during this crisis.
