The New York State Assembly issued a scathing impeachment report on Andrew Cuomo that claims the disgraced ex-gov is a serial sexual harasser who misused state resources to write a self-congratulatory book during the coronavirus pandemic.

The findings from a draft of the Assembly Judiciary Committee’s 45-page investigative report on Cuomo also blasts the former gov for deliberately undercounting nursing deaths from the virus to make himself look better.

“The report is very telling,” said Assemblyman Michael Montesano, the ranking Republican on the Assembly Judiciary Committee, who reviewed the report on Thursday.

Assembly Speaker Carl Heastie (D-Bronx) announced in March that the judiciary panel would conduct an impeachment probe of Cuomo.

The legislative body decided to complete its investigation after Cuomo resigned in August, following a separate bombshell probe by state Attorney General Letitia James’ office that concluded the then-three-term Democratic governor had harassed or mistreated 11 women — including current and former government staffers — and broke state and federal laws.

The Assembly report confirms some of the AG’s office findings, according to excerpts obtained by The Post.

“[Cuomo] engaged in multiple instances of sexual harassment, created a hostile work environment and committed sexual misconduct,” the Assembly report, prepared by the outside law firm David Polk & Wardwell said.

The Assembly report backs up the attorney general’s office findings that Cuomo abused staffer Brittany Commisso and a state trooper on his security detail, Montesano said.

The report also found that Cuomo “utilized state resources and property, including work by executive chamber staff to write, publish and promote his book for a $5.2 million personal profit.”

It also includes evidence that a senior staffer resented being asked to work on the memoir, “‘American Crisis: Leadership Lessons from the COVID-19 Crisis,” a source said.

“It’s a violation of the Public Officers Law,” Montesano said.

The Joint Commission on Public Ethics on Tuesday revoked its prior approval of the Cuomo book deal, claiming he broke ethics rules not to use staffers or other government resources in its preparation.

In addition, the report concluded that Cuomo “was not fully transparent with nursing home residents that died.”

Earlier this year, AG James issued a damning report on nursing homes that found that Cuomo and his state health department had undercounted coronavirus-related nursing home residents deaths by 50 percent.

The Post also exclusively reported in February that top Cuomo aide Melissa DeRosa told state lawmakers in a meeting that the team Cuomo “froze” and withheld the full number of nursing home deaths because they feared retribution from former President Donald Trump’s Justice Department, which was investigating deaths in New York’s long-term care facilities.

The Assembly investigation could cost up to $5.1 million, according to a contract with David Polk & Wardwell, the independent counsel.

Assembly Judiciary Committee Chairman Charles Lavine (D-Nassau) declined to comment on Thursday. He would only say that Cuomo did not personally testify.

“The investigation included interviews with 165 witnesses, along with the review of hundreds of thousands of documents, recordings, messages, memos, transcripts and other materials.” Lavine said in a statement last week.

Cuomo stepped down on Aug. 24 and Lt. Gov. Kathy Hochul became governor.

Following Cuomo’s resignation announcement, the committee suspended its impeachment inquiry but Heastie said on Aug. 16 that the committee would issue a report on its findings.

Meanwhile, Cuomo is expected to appear in Albany City Criminal Court on Jan. 7, 2022 after criminal charges for misdemeanor forcible touching was filed against him.

Cuomo and his lawyers said he did not harass any women and did not violate any laws in preparing his book.
