Donald Trump described Barack Obama as “grossly incompetent” after his predecessor criticised the US response to the coronavirus pandemic.
Asked about Mr Obama’s comments as he entered the White House on Sunday, Mr Trump said: “Look, he was an incompetent president, that’s all I can say. Grossly incompetent.”
On Saturday, Mr Obama criticised the US response to the virus without naming Mr Trump or any other officials.
In a livestreamed event featuring a number of political comments, the former president told college graduates that the COVID-19 outbreak showed many officials “aren’t even pretending to be in charge”.
“More than anything, this pandemic has fully, finally torn back the curtain on the idea that so many of the folks in charge know what they’re doing,” Mr Obama said.
“A lot them aren’t even pretending to be in charge.”
The US has become the global epicentre of the pandemic, with more than 1.5 million confirmed cases and more than 89,000 deaths.
