Sanders, 78, was also released on Friday in Las Vegas, where he was transported Tuesday after a campaign in the city during which he complained of chest pain, according to EXE News.
"After two and a half days in the hospital, I feel great. I look forward to returning to work," Sanders told the Poidu Media.
Senator Sanders spokeswoman Sarah Ford said Thursday that the man will attend the Ohio Democratic presidential nomination debate in ten days, but it remains to be seen whether that means continuing his campaign.
His main rivals are former Vice President Joe Biden (76) and Senator Elizabeth Warren (70).
Recently, Vermont Senator Sanders confirmed that he has already raised over $ 25 million in small donor money for his campaign.
The well-known politician also sought to run for Democrats in the previous election, but had to admit to his backing to Hillary Clinton in July 2016. The latter lost to Donald Trump on election night.
Although rumors circulated in the meantime that Sanders, who is celebrating his 80th anniversary in two years' time, would withdraw from major politics, he has decided not to. In February this year, he confirmed that he wanted to run for president in the 2020 elections.
"Our campaign is not just about winning Donald Trump," Sanders said. "Our campaign means changing our country and creating a government based on economic, social, racial and environmental justice."
Hello everybody! We're in Las Vegas. I'm feeling so much better.
Thank you for all of the love and warm wishes that you sent me.
See you soon on the campaign trail. vovtube.com
