The loss of his favoured candidate in Alabama’s Senate primary runoff reportedly left Donald Trump feeling “embarrassed and pissed”.

Firebrand jurist Roy Moore handily beat Senator Luther Strange in the Republican race – a blow to the party’s establishment and Mr Trump.

After the election was called for Mr Moore, Mr Trump is said to have angrily vented at his political team and Senate Majority Leader Mitch McConnell, who had encouraged the President to endorse Mr Strange, CNN reported.

A White House aide told the news outlet that Mr Trump “knew it was a mistake but one he was willing to make because Luther was loyal.”

Meanwhile, the President’s ex-chief strategist, Steve Bannon, had backed Mr Moore, waging a war on the Republican establishment.

The Breitbart executive told a crowd the night before the vote: “We did not come here to defy Donald Trump. We came here to praise and honour him.”

He continued: “We believe in America first, and conservatism because we oppose progressives and everything they stand for.”
