Donald Trump compared to Hitler as Hillary Clinton sparks outrage with 'bitter' and 'foul-mouthed' rant

She said: “When I was secretary of state, I used to talk about ‘one and done’.

“What I meant by that is that people would get legitimately elected and then they would try to do away with elections, and do away with opposition, and do away with a free press.”

Clinton added: “Hitler was duly elected. All of a sudden somebody with those tendencies, dictatorial, authoritarian tendencies, would be like ‘OK we’re gonna shut this down, we’re gonna throw these people in jail.’

“And they didn’t usually telegraph that. Trump is telling us what he intends to do.”

Allies of the 45th President were quick to slam Clinton for her comments.

Mark Burns, who is described as Trump’s Pastor, told GB News: “Hillary is a bitter, foul-mouthed, short-tempered, entitled kleptomaniac who clearly has psychological problems over her upset loss to Trump. I will be praying for her.”

He added: "Clinton's comments comparing Trump to Hitler is yet another example of Ms Clinton exhibiting her poor situational and emotional intelligence.

"Its exactly this type of insensitive remarks that sunk her ambitions to become President.

"She would do well to measure her comments twice before sharing them publicly."

A 2016 Trump campaign veteran also told GB News: "If anyone cared about what she thought, she would have been elected President."

During her appearance on ABC yesterday, Clinton made clear her warning should be taken seriously.

“Trump is telling us what he intends to do,” she said. “Take him at his word.”

Hitler, who won the 1932 German federal election, sparked the Second World War by invading Poland and orchestrated the horrific extermination of around six million Jewish people during the Holocaust.

Clinton’s comments come after it was revealed that Trump is reportedly discussing how to use the Justice Department to investigate political rivals and former allies who have been critical of him should he return to the White House.

He is also discussing invoking the Insurrection Act on his first day in office, which would allow him to use the US military domestically to quell protests and dissent.

Despite facing a number of legal obstacles, Trump is leading Joe Biden in a number of critical swing states.

An opinion poll conducted by Siena for the New York Times showed Trump ahead of the incumbent Commander-in-Chief in Arizona, Georgia, Michigan, Nevada and Pennsylvania.

Victory in the 2024 US Presidential Election would make Trump just the second President to serve two non-consecutive terms in the Oval Office.

However, the general election campaign is not yet in full swing, with both men needing to win their respective primary races before turning their attention to November 5, 2024.

A number of Republican rivals are challenging Trump for the conservative crown but the 77-year-old is streaking ahead of his opponents in the opinion polls.

Biden is not facing as much of a significant challenge and is even stronger in current Democratic Party primary surveys.
