“Democrats pledged to obtain Donald Trump’s tax returns as part of their oversight agenda, and we will hold them accountable for that promise,” said Maura Quint, executive director of Tax March. “There is no need to slow-walk this. We have played this game for years, and Donald Trump will not willingly release his tax returns. The only solution is for Chairman Neal to request his tax returns immediately.”

Along with their letter to the chairman, the progressive groups on Thursday included a draft letter that Neal could send to Treasury Secretary Steve Mnuchin demanding that he hand over Trump’s tax returns.

That draft letter to Mnuchin cites a clause in the Internal Revenue Code that requires Mnuchin to “furnish [the committee] with any return or return information” that the committee demands.
