Former US President Barack Obama and Democratic presidential candidate Joe Biden appeared at their first joint campaign event in the battleground state of Michigan on Saturday, ahead of the looming presidential election.
Biden slammed Trump for saying that doctors are taking economic advantage of the pandemic, saying that he believes that because "he doesn't do anything other than for money".
Following the speech in Flint, Trump took to Twitter to criticise both Obama and Biden for their failed policies in Flint (referring to the Flint water crisis) and for endorsing Rick Snyder, who, according to the president, was an incompetent Michigan governor.
Obama, who has been one of the most active and vocal supporters of Biden, has been against President Trump on a variety of issues, but since the start of the coronavirus pandemic, his criticism, to a large extent, have concerned Trump's handling of the virus. The former US president has recently accused Trump of being "jealous" of the COVID's media coverage and has claimed his administration's efforts to fight coronavirus are "an absolute chaotic disaster".
