Story highlights

Senate Democratic leader Chuck Schumer sought testimony from former national security adviser John Bolton, White House acting Chief of Staff Mick Mulvaney, Mulvaney aide Robert Blair and budget official Michael Duffey.

The senior US Senate Democrat on Sunday demanded testimony from four current and former White House aides in a trial expected early next year on whether to remove President Donald Trump from office, reported news agency Reuters.

Senate Democratic leader Chuck Schumer sought testimony from former national security adviser John Bolton, White House acting Chief of Staff Mick Mulvaney, Mulvaney aide Robert Blair and budget official Michael Duffey.

Schumer made his appeal in a letter to Republican Senate Majority Leader Mitch McConnell, who said last week he was coordinating with the White House.

Watch: Democrats unveil formal charges 

Democrats in the House of Representatives, where they have a majority, also sought testimony from the four men in their inquiry into whether to impeach Trump over his effort to pressure Ukraine to investigate his Democratic political rival Joe Biden. 

Mulvaney, Blair and Duffey all defied subpoenas from a House committee and Bolton was not subpoenaed.

Trump is expected this week to become the third US president to be impeached when the House votes on charges that he abused his power by asking Ukraine to investigate Biden, a leading contender to oppose him in next year's US presidential election, and obstructed Congress' investigation of the matter.

Trump has denied wrongdoing and called impeachment "a hoax."
