President Donald Trump on Sunday tore into former President Barack Obama, calling him “an incompetent president” after Obama appeared to criticize his response to the coronavirus crisis during two commencement speeches a day earlier.

Asked about Obama’s remarks, Trump told reporters on the White House lawn that he “didn’t hear it” before proceeding to bash his predecessor as “grossly incompetent.”

Until recently, Obama has largely refrained from publicly taking shots at Trump.

But earlier this month, Obama reportedly bashed the Trump administration’s response to the pandemic as “an absolute chaotic disaster” during a phone call with some of his former White House aides.

Most recently, Trump has been obsessed with pushing the “Obamagate” conspiracy theory, claiming — without evidence — that Obama led a “coup” to sabotage his presidency.
