Donald Trump has hit out at Barack Obama after the former President described his successor's handling of the coronavirus pandemic as "an absolute chaotic disaster".
Obama also said that "the rule of law is at risk" after the United States justice department said it would drop its case against former national security adviser Michael Flynn.
Taking to Twitter, Trump repeatedly used the term "Obamagate" and accused Obama of committing "the biggest political crime in American history".
