House Ways and Means Committee Chairman Richard Neal, D-Mass., has subpoenaed the Treasury Department and the IRS to follow up on his request for President Trump’s tax returns.

“While I do not take this step lightly, I believe this action gives us the best opportunity to succeed and obtain the requested material,” Neal said in a statement. “I sincerely hope that the Treasury Department will furnish the requested material in the next week so the committee can quickly begin its work.”
