During his show "Mad Money" on Wednesday, Cramer said that U.S. workers have been "bamboozled" for years into supporting trade deals for the benefit of large multinational corporations.
Cramer said "there are very few people I have met, and I've seen it on both sides, that know how to negotiate."
"Say what you want about Trump, I agree with him totally about these trade deals," he said.
"I'm with Trump on this. Look, we lose on every trade deal. I ask all these people from either party: name me one trade deal we have had a surplus on in the last decade. They can't name any," Cramer said on "Squawk Box" on Thursday. "I always find it amusing to think people don't seem to mind that we lose in these deals because we're able to export a lot of premium products that are not made necessarily by people in our workforce."
"People should understand this has been his view from day one. It has always been pro-worker," said Cramer. "Have people not been paying attention to what this man has been saying about the trade deals? He's been right the whole way."
Cramer explained further earlier in the day on "Squawk Box."
