Trump: 5% tariff on all Mexican imports

WASHINGTON -- In a surprise announcement potentially compromising a major trade deal, President Donald Trump announced Thursday he is slapping a 5% tariff on all Mexican imports to pressure the country to do more to crack down on the surge of Central American migrants trying to cross the border.

He said the percentage will gradually increase "until the Illegal Immigration problem is remedied."

Trump made the announcement by tweet after telling reporters earlier Thursday he was planning "a major statement" to be his "biggest" so far on the border.

"On June 10th, the United States will impose a 5% Tariff on all goods coming into our Country from Mexico, until such time as illegal migrants coming through Mexico, and into our Country, STOP. The Tariff will gradually increase until the Illegal Immigration problem is remedied," he wrote, "at which time the Tariffs will be removed."

Trump has accused the Mexican government of failing to do enough to crack down on the surge of Central American migrants who have been flowing to the U.S in search of asylum from countries including El Salvador, Honduras and Guatemala.

The announcement comes as the administration has been pushing for passage of the United States-Mexico-Canada Agreement that would update the North American Free Trade Agreement.

During a visit to Canada on Thursday, Vice President Mike Pence vowed the deal would be passed this year.

"Our administration is working earnestly with leaders in the Congress of the United States to approve the USMCA this summer," he said. Asked by reporters about the new tariff consideration, Pence said both Mexico and Congress need to do more and Trump is determined to use his authority to call on them to do so.
