Her supporters have called for her to run as a 2020

Democratic senator Elizabeth Warren has offered to 'put aside' her differences with Donald Trump and work with him to rebuild the US economy for 'working people'.

The liberal icon extended the olive branch after campaigning fiercely against Trump.

Her Twitter timeline is littered with attacks against him. On July 16, she said: 'Donald Trump and Mike Pence are a perfect match: Two small, insecure, weak men who use hate & fear to divide our country & our people.'

The Harvard law professor and best-selling author, who was at one point mooted as as a possible presidential candidate for the 2016 election, got behind Hillary Clinton and has consistently called out Trump.

On October 14 she wrote: 'You can't run a campaign based on hating women, African Americans, Muslims and immigrants & expect to win.'

Like millions of Americans, she has now been forced to accept that Trump could - and did - win.

On Wednesday she released a statement saying: 'It's no secret that I didn't want to see Donald Trump win yesterday.

'I'm intensely frustrated by the apparent likelihood that, for the second time in five elections, a Democratic nominee will have won the popular vote but lost the presidency in the electoral college.

'But the integrity of our democracy is more important than any individual election, and those of us who supported Hillary Clinton will respect this result.'

Warren continued: 'President-Elect Trump promised to rebuild our economy for working people, and I offer to put aside our differences and work with him on that task.

'When he takes the oath of office as the leader of our democracy and the leader of all Americans, it is my sincere hope that he will fulfill that role with respect and concern for every single person in this country, no matter who they are, where they come from, what they believe, or whom they love.'

The prospect of Warren running for president in 2020 has already began to be discussed by political commentators and her supporters.

Deputy Washington bureau chief for the Boston Globe, Matt Viser, said: 'Senators Elizabeth Warren and Tim Kaine are both up for reelection in 2018. And they also may both be carefully eyeing 2020.'

A hypothetical 2020 presidential campaign for the Massachusetts senator started being talked about on social media as soon as Trump's win on election night became clear.

Fellow liberal Bernie Sanders has also vowed to work with Trump to help the working class, but will 'vigorously' oppose any racist, sexist or xenophobic policies promised by the president-elect.

The independent Vermont senator noted that Trump 'tapped into the anger of a declining middle class that is sick and tired of establishment economics, establishment politics and the establishment media.'

He said that if Trump 'is serious about pursuing policies that improve the lives of working families in this country, I and other progressives are prepared to work with him.'

Sanders ran against Clinton for the Democratic presidential nomination, and supported her candidacy after she won that race.

In the wake of Clinton's shocking defeat, calls have also grown on Twitter for Sanders to run for president again in 2020.
