Here's why Cramer is blown away by Trump's Cabinet picks for Treasury and Commerce

CNBC's Jim Cramer said Wednesday he was taken aback by Steven Mnuchin and Wilbur Ross' proposed policy agendas under a Trump administration.

"Look, we're going to do responsible tax cuts. Everybody wants tax cuts," Cramer said on "Squawk on the Street." "I was blown away. These two guys are basically saying, listen, we have a traditional Republican agenda — bring money back. You know, try to help the middle class, maybe give some breaks for the rich, but take them back in terms of the way it's done. Republican agenda."

Cramer spoke after Mnuchin confirmed on CNBC that Donald Trump said he intends to name him as Treasury secretary and Ross for Commerce. In an exclusive interview on "Squawk Box," Mnuchin said he wants to slash taxes across the board and added he is confident the new administration would be able to expand gross domestic product growth.

"Our most important priority is sustained economic growth, and I think we can absolutely get to sustained 3 to 4 percent GDP, and that is absolutely critical for the country," Mnuchin said.

Cramer said the proposals by Mnuchin and Ross — in line with Trump's previous statements — seemed much more responsible. Cramer called Trump's choices "sophisticated" and Wall Street businessmen who understand the environment.

"Going in, I had felt that President-elect Trump stood for big tax cuts and lots of spending," Cramer said. "Today, I felt like he stands for bring that money back, repatriate nice tax cuts for the middle class and things will work out."

He added: "I think the ultimate takeaway is, Mnuchin and Wilbur Ross are business people. ... I mean, pure business people who have done great business in their life made a lot of money."
