Chairman of the Senate Finance Committee Orrin Hatch, R-Utah, said that President Trump may need to surrender his tax returns, following a report that President Trump and his siblings participated in potentially fraudulent tax maneuvers.

Hatch said that he was willing to examine allegations detailed in the New York Times report, and said that Trump’s tax returns may need to be handed over in the process. Trump infamously did not disclose his tax returns when he was running for president in 2016, and has refused to do so since.

“I’d be happy to look into it," Hatch said about the Times report, per CNN. "But right now, I don’t know enough about it.”

“He may have to give up those returns,” Hatch added.

Senate Finance Committee ranking member Ron Wyden, D-Ore., also called on the IRS to launch an investigation into the allegations.

Trump and his siblings reportedly established a fake corporation to conceal millions of dollars in taxable income they received as gifts from their parents, according to the New York Times. The Times also reported that Trump assisted his father in making inappropriate tax deductions, among other things.

Trump refused to comment to the Times. However, Trump attorney Charles Harder asserted that the allegations were “100 percent false, and highly defamatory.”

"There was no fraud or tax evasion by anyone," Harder said in a statement to the Times. "The facts upon which the Times bases its false allegations are extremely inaccurate."

Harder also said that Trump has “virtually no involvement whatsoever with these matters” and claimed that other Trump family members “who were not experts” managed these issues.
