Ingrid Lewis-Martin, a former top aide to Mayor Eric Adams, is expected to be indicted Thursday, sources tell NY1.

Lewis-Martin stepped down from her post Sunday as Adams' chief adviser, a role that made her one of the most powerful officials in City Hall.

The specific charges against Lewis-Martin were not publicly announced and remain unclear, but Arthur Aidala, Lewis-Martin’s lawyer, said on Monday that he believes the charges will allege that Lewis-Martin received illegal gifts. 

Speaking to reporters Monday, Lewis-Martin said she was being “falsely accused” of something.

"I don’t know exactly what it is, but I know I was told it's something illegal. And I have never done anything illegal in my capacity in government," she said.

“I have never taken any gifts, money, anything. I have not made any arrangements in advance to take any gifts or money or to have any gifts or money given to a family member or friend in order for me to do my job,” Lewis-Martin added.

Lewis-Martin’s phones were seized by the Manhattan district attorney's office in September, and she was served with a subpoena. A search warrant was also executed at her home. 

The charges against Lewis-Martin come as the Adams administration has been roiled by criminal investigations.

Adams, a Democrat, has himself been charged with conspiracy, wire fraud and bribery charges in an unrelated federal case scheduled for trial next April. He has pleaded not guilty.

Lewis-Martin, 63, has been one of the mayor's closest confidants throughout his political career, serving in senior roles under Adams as he ascended the ranks of government in New York over the past nearly two decades. She worked with Adams when he served in the state Senate and at Brooklyn Borough Hall. Her husband, Glenn Martin, also served with Adams in the NYPD.

Hours after that search, Lewis-Martin appeared on a radio show hosted by Aidala to discuss the investigation, telling her attorney, “I do believe that in the end that the New York City public will see that we have not done anything illegal to the magnitude or scale that requires the federal government and the DA’s office to investigate us.”

Aidala told reporters on Monday that he believed prosecutors in Manhattan were charging Lewis-Martin to get her to cooperate against Adams. In an unrelated news conference that day, Adams described Lewis-Martin as a “longtime friend and sister.”

Adams was charged in September with accepting luxury travel perks and illegal campaign contributions from a Turkish official and other foreign nationals looking to buy his influence.

The investigation into Adams became public late last year after federal agents searched the home of his top fundraiser, Brianna Suggs. Lewis-Martin has referred to Suggs as her goddaughter.

Since then, the Adams administration has been enveloped by a series of searches and seizures from investigators, leading to the resignations of top officials, including his police commissioner, schools chancellor, multiple deputy mayors and his director of Asian affairs.
