Mark Warner Was Interviewed on CBC News Network About President Trump’s Musing About Not Renewing the USMCA

Mark Warner was interviewed on CBC News about U.S. President Trump’s musing about not “renewing” the USMCA, why that doesn’t mean the U.S. is going to “withdraw” from the agreement and why annual reviews were always the most likely landing zone (but poking the bear remains risky).
