(CNN) - Democratic Senator Sherrod Brown of Ohio says the U.S. needs to reopen discussions with Mexico and Canada on trade. And he rejects President Trump's contention their new trade agreement is final.
Trump, Canadian Prime Minister Justin Trudeau and just-departed Mexican president Enrique Peña Nieto signed the NAFTA replacement at a ceremony -- during the recent G20 Summit.
Aboard Air Force one after the G20, Trump told reporters he would be "formally terminating NAFTA shortly" and sending the new agreement to Congress for approval.
Brown gave his take on CNN's "State of the Union" on Sunday.
Jake Tapper, host of CNN's State of the Union, asked, “I just want to get you firmly here. You're going to vote no on the USMCA?"
"No, I don't. The work's not done yet. I understand the president said it's final. The president needs to talk to Congress on this and we can go back to the table with the Mexicans and the Canadians and do stronger labor. Mexico hasn't even passed its its promised strengthening of labor standards and labor law that it said it would do during these negotiations there is now a new Mexican president who who is more pro worker than the outgoing president that signed USMCA. I'm hopeful with the House of Representatives where it is, with the labor movement, with with labor with workers all over the country telling me they want stronger labor enforcement standards - you don't just sign this away because this does this doesn't live up to the promise the president said that it would be a renegotiated NAFTA helping workers and stopping outsourcing because it doesn't do that yet. I'm hopeful that it will,” Senator Sherrod Brown answered.
On another topic, Brown said he has not written off the possibility he will challenge Trump in 2020. He said he still did not know whether he would run, but made the case that his message would be a strong one nationwide.
