After an almost week-long disappearance Joe Biden posted a video on Twitter to address the Trump administration’s handling of the Covid-19. crisis

However, his incoherent ramblings were greeted with a mixture of mockery and concern.

RT reports: Biden sounded tired and slow as he spoke while standing in front of what appeared to be a green screen with a set of bookshelves digitally imposed behind him.

He criticized US President Donald Trump and Senate leader Mitch McConnell for “trying to put a corporate bailout ahead of millions of families” and urged “aggressive measures” to help small US businesses, workers and communities suffering during the Covid-19 outbreak.

Biden had reportedly addressed his donors for a “virtual fundraiser” on Sunday, though no footage of that event has found its way online. Prior to that, the former VP and candidate for president had not appeared in public since Tuesday, amidst the rapidly progressing national coronavirus crisis. The disappearance, at such an unusual time, prompted many to question whether he had suffered health problems himself.

At one stage, his campaign excused his absence from public view by suggesting it was difficult to record videos in his home because there “aren’t particularly high ceilings, which can make lighting a challenge,” according to ABC News.

So it was little wonder that most were not impressed with his comeback video on Monday, which immediately raised eyebrows – and produced plenty of jokes –  on social media.
