Democrats will 'never' see Donald Trump's tax returns, says White House chief of staff

Democrats will "never" see US president Donald Trump's tax returns, said White House chief of staff Mick Mulvaney as a new front opened in the confrontation between the administration and Congress.

Mr Mulvaney accused Democrats of engaging in a "political stunt" and wanting "attention" after the chairman of the House Ways and Means Committee, Representative Richard Neal, asked the IRS (Internal Revenue Service) to provide six years of Mr Trump's personal tax returns and the returns for some of his businesses.
