The Internal Revenue Service’s acting commissioner is resigning over a deal to share immigrants’ tax data with Immigration and Customs Enforcement for the purpose of identifying and deporting people illegally in the U.S. Two people familiar with Melanie Krause’s decision confirmed the intended resignation to The Associated Press on condition of anonymity because they were not authorized to speak publicly about it.

The Internal Revenue Service’s acting chief counsel, William Paul, has been removed from his role at the agency and replaced by Andrew De Mello, an attorney in the chief counsel’s office who is deemed supportive of Elon Musk’s Department of Government Efficiency, according to two people familiar with the plans who were not authorized to speak publicly.
