A top adviser to New York City Mayor Eric Adams abruptly resigned on Sunday amid a federal investigation into a corruption and bribery indictment against Adams.

The adviser, Ingrid Lewis-Martin, has had her phones seized and her home searched as part of the investigation. She issued a lengthy statement regarding her departure in tandem with Adams on Sunday, saying she plans to spend more time with her family.

"To my political partner, brother, and friend, Mayor Eric Adams: I thank you for seeking me out, way back in 2004, and asking me to run your Senate campaign. I thank you for seeing in me things that I did not see in myself," Lewis-Martin said. 

"I extend humble gratitude to you for encouraging me to be my authentic self and for having my back during some trying times. As you would say, this has been a good ride; I will use author’s license and say that this has been an amazing ride," she added.

Adams' statement echoed his aide's friendly tone.

"Ingrid has not been just a friend, a confidant, and trusted adviser, but also a sister. We’ve always talked about when this day would come, and while we’ve long planned for it, it is still hard to know that Ingrid won’t be right next door every day," Adams said.

"I, and every New Yorker, owe her a debt of gratitude for her decades of service to our city. While she gets to spend a lot more time with her granddaughter, I know Ingrid will still stay involved in moving our city forward from the sidelines as she continues to root for our administration and our city," he added.

The announcement comes just days after Adams met with incoming border czar Tom Homan. Adams has adopted a more aggressive immigration stance following President-elect Trump's win in November.

"It went great," Homan told Sean Hannity on Thursday night. "Look, I sat down with the mayor for well over an hour. He gets it. And today he proved that as the mayor in New York City, he's more concerned with public safety than politics. I wish the mayor of Chicago and the San Diego City council mayor and Governor Pritzker, I wish they'd all take a page out of Mayor Eric Adams' playbook."

Homan recalled how the "ex-cop" came out of Adams during their closed-door meeting Thursday in New York.

"He really cares about public safety, and he's putting politics aside. He wants to help ICE take criminal threats off the street. He wants to help ICE look for national security threats. He wants to help ICE find over 340,000 missing children, which many are going to be in the city. So a great meeting."
