COHOES — Gov. Andrew Cuomo, reacting to Sunday's Times Union report that Cohoes Mayor Shawn Morse is alleged to have used physical violence against his wife and daughter, urged Morse to resign and said State Police were reopening their investigation of the mayor's conduct in light of the new allegations.

"The frightening and egregious evidence of domestic violence against Mayor Morse, as documented in recent media reports, cannot be ignored," Cuomo said in a statement released Sunday afternoon. Both are Democrats.

"Given the documented evidence presented in these reports, it is clear ‎he cannot continue to serve and must resign," the governor said. "The New York State Police have reopened their investigation ‎based on new reported evidence."

Byron Brown, the chairman of the state Democratic Party, echoed Cuomo's resignation demand, calling Morse "unfit to serve.'

The renewal of the State Police investigation wasn't Morse's only potential legal problem to emerge on Sunday.

Colonie police on Sunday confirmed that they are investigating a complaint his wife, Brenda Morse, filed on Friday accusing her estranged husband of grabbing her, causing bruises, and spitting in her face when they met at a Wolf Road restaurant last week to discuss the terms of their separation and child custody issues.

Police opened the investigation after interviewing Brenda Morse and documenting bruises on her arm and shoulder, and a scratch on her left ear.

Morse on Sunday said he would not resign before his term ends next year. He called on Cuomo to leave office because "he's the most corrupt governor in America."

"When the governor starts using the Times Union as his source of fact then he should start calling out the people in his cabinet that have been arrested for corruption all across New York rather than pretend like he knows nothing about it," Morse said.

Cuomo spokesman Richard Azzopardi shot back: "No amount of baseless name calling will detract from the fact that the evidence presented shows this mayor is a disgrace and isn't fit to lead."

Earlier Sunday, Morse faulted the Times Union for reporting the abuse allegations, claiming they were based on the "mental illness and drug addiction of my wife." He repeated that assertion in an interview Sunday.

The article, published Sunday, detailed allegations that Morse used physical violence on multiple occasions against his wife and younger daughter. The article was based on documents including an affidavit and child protective services reports obtained by the Times Union.

The new information expands the number of women that Morse has been accused of physically abusing. Colleen Keller, a former girlfriend, went public last year and said that Morse had repeatedly abused her in the 1990s, including an incident where he grabbed her by the throat and lifted her off the ground.

Abuse allegations have dogged Morse since his wife called 911 last November, marking the first time that allegations of domestic abuse against Morse became public.

Cohoes police quickly dismissed Brenda Morse's allegations after responding to the call, saying they noticed a scratch on Morse's face but did not see any visible injuries on Brenda Morse. The case was turned over to the State Police.

Last week, a spokesman for the State Police said they had "thoroughly investigated this case and did not develop probable cause to make an arrest. However, the case will be reopened if additional information is developed, and an arrest will be made if warranted."

The Albany County District Attorney's office began investigating how the Cohoes Police Department handled allegations of abuse by Morse, but the status of that probe is unclear.

The documents shared with the Times Union include an affidavit — never filed in court — in which Brenda Morse accused her estranged husband of assaulting her throughout their 19-year marriage. The document attributes to Brenda Morse statements that her husband "has punched me, kicked me, slapped me, broken a jewelry box over my head, broken a picture frame across my back, thrown me down a flight of stairs, and slammed my face against a concrete surface, causing a bloody nose and facial cuts."

Brenda Morse, who is pursuing a divorce, declined to talk to the Times Union on the advice of her attorney. But she confirmed that the accusations contained in the affidavit and the child protective services reports are accurate, and that she stands by the allegations she made against her husband.

The child protective services reports, filed by investigators in Rensselaer County because of Shawn Morse's political ties in Albany County, detail allegations that he regularly used physical violence against his younger daughter, now 16, including pulling her hair, throwing her to the ground, choking her and punching her in the head.

It's unclear why CPS investigators became involved, but during at least one interview Morse's daughter was accompanied by Heather Bradt, a math teacher and tutor at Cohoes High School who has mentored Morse's daughter. That interview took place March 24, 2017, at the Cohoes Public Library, according to the report.

During the interview, a CPS investigator wrote in a report that the daughter, then 15 — whose name is being withheld by the Times Union — recounted how a few days earlier her father allegedly attacked her unprovoked at the family's residence following a heated argument he had with his wife in the middle of the night, the document states.
