Canadian Prime Minister Justin Trudeau on Tuesday thanked House Speaker Nancy Pelosi for phoning him to discuss what he called “the new NAFTA” — the trade deal Canada renegotiated with the US and Mexico.

“@SpeakerPelosi and I spoke today about moving forward with the new NAFTA in order to support good, middle class jobs and create opportunities for people on both sides of the border. Thanks for the call, Nancy. Looking forward to our continued work on this,” Trudeau tweeted, not using the name for the proposed deal touted by President Trump, the United States/Mexico/Canada Trade Agreement.

The California Democrat’s office did not immediately return a request for comment on the call.

The Canadian PM’s tweet came a day after Trump — on Labor Day — berated AFL-CIO President Richard Trumka, who told Fox News that unions would not back the administration’s proposal in its current form.

“If Mexico can’t enforce their own agreement, this agreement will never work because their wages will be artificially low and they will suck jobs and capital out of the United States,” Trumka said.

“An unenforceable trade deal is a windfall for corporations and a disaster for workers.”

The president saw it another way, suggesting his members withhold their union “$Dues” because they’re “not worth it!”

“Just watched AFL-CIO President Richard Trumka on @FoxNews and thought to myself how different he is on TV than he is when he is with me at the White House. Likes what we are doing until the cameras go on. We got robbed on Trade and everything else while his Dems just sat back and watched,” Trump tweeted.

“NAFTA is the worst Trade Deal ever made — terrible for labor — and Richard let it stand. No wonder unions are losing so much. The workers will vote for me in 2020 (lowest unemployment, most jobs ever), and should stop paying exorbitant $Dues, not worth it!”

Whether its called “the new NAFTA” or “the USMCA,” the president’s proposal appears stalled in Congress, where Democrats cite labor’s opposition and other concerns as roadblocks.

And despite US Chamber of Commerce CEO Tom Donohue’s prediction Tuesday that there were enough votes in the House to pass it, a leading Democrat said otherwise.

Connecticut Rep. Rosa DeLauro told The Middletown Press in an interview Tuesday that House Democrats were unlikely to back Trump’s proposal.

“When we get to where we need to get to, we will move,” said DeLauro, part of a House Democratic group negotiating with the White House on changes to the deal.

“We’re not there yet. And that’s critically important to understand.”

Both Trump and Trudeau hailed the trilateral trade agreement at the G-7 summit last month in Biarritz, France.
