Former President Donald Trump is no longer in the White House and, technically speaking, no longer a New York resident. 

And yet a battle over the disclosure of his income taxes is still raging as Trump faces investigations in New York. 

Trump has filed a legal challenge to a state law that would enable state officials to turn over his state tax returns to Congress, approved after the then-candidate and later president broke with years of tradition and did not make his taxes public.

The law, known as the TRUST Act, would not automatically trigger the release of Trump's New York tax returns, but instead allow congressional committees access to it. 

Trump's attorney this week aruged the law no longer applies to Trump because he is now a former president. 

“While the Trust Act is not the clearest statute, the best reading is that it does not apply to former presidents,” Trump's lawyers wrote to a federal judge this week. 

But the original sponsor of the measure, state Sen. Brad Hoylman, defended the provision's continued application to Trump. Hoylman is now a candidate for Manhattan borough president and is holding an event later Thursday to further defend the law.

“The TRUST Act explicitly applies to New York State tax returns — including past returns — filed by elected officials including the President of the United States. Nothing in the statute suggests that it no longer applies once a covered individual leaves elected office," Hoylman said in a statement. "Trump has repeatedly demonstrated that he’s desperate to avoid scrutiny of his tax returns, so I’m not surprised by his latest attempt to wriggle out of the plain language and clear legislative intent of the law. The District Court should reject this specious argument, and the House Ways & Means Committee should make a formal request for Trump’s tax returns if they are continuing their investigation into his finances.”

Trump is suing the state Department of Taxation and Finance, New York Attorney General Letitia James and the House Ways and Means Committee to block the measure being applied to his tax returns.
