President Trump lashed out at Democrats, who he said are “frozen with hatred and fear,” a day after ​House Speaker Nancy Pelosi launched an “official impeachment inquiry” into him. ​

“There has been no President in the history of our Country who has been treated so badly as I have. The Democrats are frozen with hatred and fear.

“They get nothing done​,” the president wrote on his Twitter account Wednesday. ​”This should never be allowed to happen to another President. Witch Hunt!”​

​Pelosi announced on Capitol Hill on Tuesday afternoon that the House would move ahead on the impeachment inquiry after Trump made a phone call to Ukrainian President Volodymyr Zelensky to investigate possible corruption involving Democratic presidential candidate Joe Biden and his son Hunter.

“The president must be held accountable. No one is above the law,” the California Democrat said.

Pelosi made the announcement just hours after the president addressed the United Nations General Assembly.

T​rump ripped Democrats for their timing in a tweet late Tuesday. ​

“Such an important day at the United Nations, so much work and so much success, and the Democrats purposely had to ruin and demean it with more breaking news Witch Hunt garbage​,” he posted. “So bad for our Country!​”​

The president returns to the world stage again Wednesday, when he’s expected to meet with a number of leaders, including Zelensky.

Reports based on a whistleblower’s account of the phone call said Trump stalled nearly $400 million in US military aid to Ukraine to pressure Zelensky to open the probe into the Bidens.

Trump has admitted talking to Zelensky about the Bidens, but said he held up the aid because he believed that European countries were not paying their fare share of Ukraine’s defense, denying there was a quid pro quo.

The Eastern European country is fighting Russian-backed insurgents.

The president said he would release both a transcript of the July 25 call with Zelensky and the whistleblower’s report Wednesday.

Biden, who has denied any wrongdoing, said he would back impeaching Trump if the president stonewalls lawmakers investigating him.

​”​I can take the political attacks. They’ll come and they’ll go, and in time they’ll soon be forgotten,” ​the former veep said Tuesday. “But if we allow a president to get away with shredding the United States Constitution, that will last forever.”
