The new subpoenas were issued on Friday, despite the Treasury secretary’s repeated refusals to hand over six years of the president’s personal and business tax returns.
In a statement on the latest subpoenas, Neal said, “While I do not take this step lightly, I believe this action gives us the best opportunity to succeed and obtain the requested material.”
Thus far, subpoenas have been issued from the judiciary, oversight and reform, ways and means, financial services, and intelligence committees.
A subpoena has also been served on the president’s son, Donald Trump Jr.
A recent exposé by the New York Times showed that Trump’s core businesses operated at a massive loss between 1985-1994. In response, the president claimed that the $1bn loss was deliberately calculated “for tax purposes”.
