Giuliani is the best lawyer that Trump could hire… At every stage he has managed to implicate the president, and others, further… He has most recently ensured Pompeo will be in the spotlight of investigations.

‘Shut up, moron. Shut up. Shut up’

Rudy Giuliani hurled abuse at a fellow Fox News guest, calling him a “serial liar” and a “moron” as the president’s opponents pledged to seek Donald Trump’s removal from office.

With the threat of impeachment hanging in the air, Mr Giuliani’s outburst on Fox News’ The Ingraham Angle came as he looked to defend Donald Trump and himself from allegations the president had offered to trade aid for political favours with the government of Ukraine.

The lawyer lambasted fellow guest Chris Hahn, a former aide to senior Democrat Chuck Schumer, saying he should “sue him for libel” after the liberal commentator implied Giuliani was asked by the US State Department “to dig up political dirt on Trump’s opponent”.

“Shut up moron, shut up” the president’s legal representative shouted over the left-wing pundit. “You don’t know what you’re talking about idiot. You’re just lying…just keep your lying mouth shut.”
