U.S. House Ways and Means Committee Chairman Richard Neal on Friday subpoenaed President Donald Trump's tax returns, giving the U.S. Treasury and Internal Revenue Service one week to turn over the tax records.

In the latest salvo of a political battle widely expected to end in federal court, Neal issued separate subpoenas to Treasury Secretary Steven Mnuchin and IRS Commissioner Charles Rettig that seek six years of Trump's individual and business tax returns. The officials have until 5 p.m. on May 17 to produce the material.

Trump is stonewalling oversight investigations by Neal and five other Democratic committee chairs in the House of Representatives, prompting Democrats to warn Trump officials that they could face contempt citations along with heavy fines and even impeachment by defying congressional subpoenas.
