Rep.-elect George Santos says he will address questions raised about his background next week.

MORE: Questions remain over Rep.-elect Santos' resume following New York Times report

Santos, the Republican elected to represent New York's 3rd Congressional District, is under fire following a New York Times report that called into question claims he had made about his personal history, including where he has worked, where he went to school and where he lives.

In a tweet, Santos wrote in part, "I want to assure everyone that I will address your questions and that I remain committed to deliver the results I campaigned on; public safety, inflation, education and more."

Santos is also now facing scrutiny over his claimed Jewish upbringing. On the campaign trial, Santos spoke about his grandparents escaping the Holocaust and fleeing to Brazil.

According to reports, genecology records reveal Santos' maternal grandparents were born in Brazil before the Nazis rose to power.

Great Neck resident Ron Guggenheimer says if Santos lied about his family history, it's offensive to the millions of Jewish people who died in the Holocaust and to survivors, including his parents.

"It's just unthinkable that somebody would mischaracterize or make up their ancestry for political gain or any other gain," Guggenheimer said.

Nassau Executive Bruce Blakeman, the county's first Jewish county executive, said that we need to hear from Santos about the allegations.

"It's one thing for a politician to embellish their resume, most politicians do, it's another thing to say something that's completely untrue," Blakeman said. "There's accusations out there, so I think Mr. Santos has to stand up and tell the public what is true and what is not."

Blakeman appeared with Santos at Hanukkah celebrations just a day before the New York Times report broke.

New York state Attorney General Letitia James launched an investigation into the accusations.

Nassau County Republican Committee Chairman Joseph Cairo Jr. released a statement, saying "Congressman-Elect Santos has tweeted a public statement, announcing that he will respond next week to the issues that have been raised by various media outlets. While I have indicated that the Congressman-Elect deserves a reasonable amount of time to respond to the media, voters deserve a sincere accounting from Mr. Santos. I will be listening attentively, and I want to hear meaningful remarks from George Santos."

News 12 reached out to Santos several times for comment and was still waiting to hear back as of 5 p.m. Thursday.
