White House National Economic Council Director Larry Kudlow said the impeachment inquiry of President Donald Trump is “doomed to failure.”

“Frankly, judging from the release of the letter which explains a lot of good things and all the second-, third- and fourth-hand stuff from this alleged whistle-blower, I don't know,” Kudlow predicted to Fox Business Network, saying he personally thinks impeachment is “doomed to failure.”

Meanwhile, investors are starting to prepare for a long U.S. impeachment process that could drag into 2020, Reuters explained.

The decision by the House of Representatives to begin impeachment inquiries that could end in a vote to remove Trump from office added more uncertainty to a stock market that is already struggling under the weight of issues ranging from the U.S.-China trade war to Federal Reserve monetary policy.

Investors expect impeachment efforts ultimately to fail, given the unlikelihood that a supermajority of the Republican-controlled Senate votes to remove President Trump from office. However, they still see numerous ways the proceedings could spill over into financial markets.

With only two impeachment proceedings in the modern era to draw from, market history offers few guides.

Earlier Thursday on Fox News Channel’s “Fox & Friends,” Kudlow shared his very optimistic view on the U.S. economy.

Kudlow said the economy was headed in the direction of a “mini-comeback,” citing housing and manufacturing data.

“Housing, manufacturing starting to boom again in July and August,” he said.

“The president mentioned that in his presser yesterday. It looks like the U.S. economy is in a turning zone back up," Kudlow said.

"And our policies of tax cuts and deregulation and lowering trade barriers and energy are working. And if we get some help from Europe, maybe they would emulate our supply-side policies," he said.

"The whole world could move in prosperity. But the USA is now having a mini-comeback inside of a long prosperity cycle, and it’s terrific news, and I don’t want to lose that,” he said.
