Trump fires back at AFL-CIO chief Trumka: 'No wonder unions are losing so much'

President Trump on Monday lashed out at AFL-CIO President Richard Trumaka a day after the labor union leader criticized Trump's trade deal in a Fox News interview.

Trump, in a Labor Day morning tweet, claimed that Trumka doesn't share the same critique of Trump's trade deal when "he is with me at the White House."

"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," Trump tweeted.

The president targeted the AFL-CIO head after Trumka said that unions were not ready to back the president's "uneforceable" replacement for the North American Free Trade Agreement.

"We got robbed on Trade and everything else while his Dems just sat back and watched. 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!"

"An unenforceable trade deal is a windfall for corporations and a disaster for workers,” Trumka said Sunday of the proposed United States–Mexico–Canada Agreement (USMCA).

He also criticized Trump's handling of China, saying to take on the nation "it has to be a multilateral approach … one country can’t take on China.”

The White House and Trump have pushed back on claims that the tariffs on Chinese goods will hurt consumers or farmers, arguing that it will only impact China.

Trumka and Trump have feuded in the past. Trumka has criticized NAFTA, but has repeatedly said that Trump’s replacement USMCA deal is worse and said unions are united against supporting it. Trumka recently led his own delegation to Mexico to discuss the deal.
