House Judiciary Committee Chairman Jerry Nadler announced Tuesday that he will be holding the panel’s first impeachment hearing next week — and invited President Trump to attend.

In a letter addressed to the commander in chief at the White House, the Manhattan lawmaker said that both the president and his lawyer would be welcome to attend the hearing.

The planned session comes after an initial investigation by the House Intelligence Committee, led by Rep. Adam Schiff (D-Calif.), mainly into Trump’s alleged push to get Ukraine to investigate political rival Joe Biden in exchange for US military aid.

It will now be up to the Judiciary Committee to weigh the Intelligence panel’s findings on what, if any, formal charges should be brought against Trump. It is unclear if the Judiciary panel has a report from Intelligence on its findings yet.

The full House would then vote on whether to impeach the president, should charges be filed.

The Judiciary proceeding is officially titled, “The Impeachment Inquiry into President Donald J. Trump: Constitutional Grounds for Presidential Impeachment” and is set to begin on Capitol Hill next Wednesday.

“I write to ask if . . . you and your counsel plan to attend the hearing or make a request to question the witness panel,” Nadler wrote the president.

Nadler said the hearing would provide “an opportunity to discuss the historical and constitutional basis for impeachment as well as the Framers intent and understanding of terms like ‘high crimes and misdemeanors.’ ”

Nadler requested that Trump RSVP by 6 p.m. Sunday.

Trump has said he would “strongly consider” giving written testimony to House impeachment investigators after Speaker Nancy Pelosi challenged him to testify if he thought the proceedings were unfair, as he has routinely charged.

On Tuesday, Trump tweeted that he would “love to have Mike Pompeo, Rick Perry, Mick Mulvaney and many others testify about the phony Impeachment Hoax.”

“It is a Democrat Scam that is going nowhere but, future Presidents should in no way be compromised. What has happened to me should never happen to another President!” he added.

The president has denied wrongdoing.

New poll numbers show that the Intelligence Committee’s impeachment inquiry failed to move the needle among American voters after two weeks of public hearings.

A CNN poll conducted Friday through Sunday and released Tuesday shows that the same number of Americans — 50 percent — back impeaching Trump as the poll found in October.

The poll also found that 43 percent don’t believe Trump should be removed from office — again the same as the October survey.
