Standoff intensifies as Democrats subpoena Trump tax returns

US House Democrats issued subpoenas Friday against top government officials demanding President Donald Trump's tax returns, the latest twist in the sharpening battle between the White House and opponents in Congress.House Ways and Means Committee chairman Richard Neal said he subpoenaed Treasury Secretary Steven Mnuchin and Internal Revenue Service commissioner Charles Rettig after they missed two congressional deadlines to turn over six years of the president's personal and business tax data.
