Washington: Social networking giant Facebook has teamed up with ABC News to live stream all US presidential debates online. Viewers will be able to ask questions and make comments on Facebook Live coverage. "The debates will also be preceded by a new show called Strait Talk and then followed by another Facebook Live show hosted by Nightline co-anchor Dan Harris," The Verge reported on Wednesday. The first debate is in Hempstead, New York, on September 26. In July this year, Democratic presidential nominee Hillary Clinton's team took to Facebook to counter her Republican rival Donald Trumps' lawsuits. Over 670,000 people have watched the live stream till date, which lasted for four hours. ABC News also live streamed both Democratic and Republican national conventions on Facebook in May this year that received 28 million video views.
