White House economic adviser Larry Kudlow said the "single biggest event" of 2018 is "an economic boom that most people thought would be impossible."

Addressing reporters in Washington, Kudlow said President Trump's policies have led to a positive economic outlook.

In a "Fox & Friends" interview earlier Thursday, he said that the Obama White House "mantra" was that America could never surpass 2 percent gross domestic product (GDP) growth.

"Now we are growing at 4 percent, and they’re saying Obama should take credit. In other words, we couldn’t grow at 2, but uh-oh we just doubled that to 4, so we’re going to give credit to our man, No way," Kudlow said.

He said Trump deserves credit for lowering tax rates and removing regulations on business.

Kudlow also reacted to New York Gov. Andrew Cuomo (D) saying that "America was never that great."

He said he knew Cuomo's father, former Gov. Mario Cuomo (D-N.Y.) "very well," and that the elder Cuomo "loved America" -- and despite being a liberal Democrat -- was not seen as divisive among many Republicans.

"Why in the world Andrew – why Andrew would make a statement like that is beyond belief to me. I just don’t get it," Kudlow said.
