A group of 19 U.S. senators urged the Trump administration to push back the planned June 1 start date for the United States-Mexico-Canada Agreement (USMCA), saying the short lead time would add undue pressure to U.S. companies during the spread of the coronavirus, according to Reuters.

In a letter to U.S. Trade Representative Robert Lighthizer, the senators, led by Republican Senate Finance Committee Chairman Chuck Grassley (R-IA) and Ranking Member Ron Wyden (D-OR), said the new trade deal, which replaces the North American Free Trade Agreement (NAFTA), should not enter into force until Mexico and Canada are in full compliance with their commitments.
