Bernie willing to join hands with Hillary to beat Trump

Following President Barack Obama and Vice President Joe Biden formally endorsing Hillary Clinton for president, Bernie Sanders affirmed to work with Hillary to beat Donald Trump in the U.S. polls.

According to CNN, Sanders' decision to continue his White House bid even after Clinton became the party's presumptive presidential nominee has had Democrats on high alert as they seek to quickly change gears and take on Trump, the presumptive Republican presidential nominee.

Emerging from the White House after a meeting with Obama, Sanders warned that Trump as President would be a "disaster" and that he would "work as hard as I can to make sure that Donald Trump does not become president of the United States."

"I look forward to meeting with (Clinton) in the near future to see how we can work together to defeat Donald Trump and to create a government which represents all of us and not just the 1%," Sanders told reporters.

Earlier, the White House released a video in which Obama formally endorsed Clinton and acknowledged the historic achievement of her becoming the first woman to win a major party's presidential nomination.

He will join Clinton on the campaign trail for the first time next week in Wisconsin.

"I don't think there's ever been someone so qualified to hold this office," Obama said in the video.

He also thanked Sanders for running an "incredible campaign" and for shining a spotlight on issues such as economic inequality and the influence of money in politics.

Sanders' meeting with Obama and his public remarks afterward come just days after Sanders declared that he intends to continue his 2016 campaign.
