Bernie Sanders, 77, announces he will run for US President once again in 2020

US SENATOR Bernie Sanders has announced he will seek the Democratic nomination for a second time ahead of the 2020 presidential race.

The 77-year-old lost out to Hillary Clinton in 2016 despite a huge swell in grassroots support for his self-styled 'Democratic socialist' movement, before Donald Trump beat Clinton in the presidential election later that year.

In an email to his supporters announcing his latest bid for the White House today, the Vermont senator took aim at President Trump who he called "the most dangerous president in modern American history".

Sanders added: "Three years ago, during our 2016 campaign, when we brought forth our progressive agenda we were told that our ideas were ‘radical’ and ‘extreme’.

"Well, three years have come and gone. And, as result of millions of Americans standing up and fighting back, all of these policies and more are now supported by a majority of Americans.

"Together, you and I and our 2016 campaign began the political revolution. Now, it is time to complete that revolution and implement the vision that we fought for."

Although Sanders is an independent senator and not a member of the Democratic Party in the Senate, he often aligns with them on progressive issues such as Medicare for All and free college tuition.

He joins what is becoming an increasingly crowded field of candidates seeking the 2020 Democratic nomination - a group which already includes Kamala Harris, Cory Booker, Elizabeth Warren, Kirsten Gillibrand and Amy Klobuchar.

Born to Jewish parents with roots in Poland and Russia, Sanders grew up poor in Brooklyn, New York and became involved in the Civil Rights movement while a student at the University of Chicago.

He was elected Mayor of Burlington, Vermont in 1981 before becoming the state's sole representative in Congress in 1990. He served there until he joined the Senate in 2006.

Following the election of President Trump, Sanders published a book titled Our Revolution: A Future to Believe In.

He has four children and is married to Irish-American Jane O'Meara, a former president of Burlington College and his closest adviser.
