Mr Schmidt described Mr Trump’s response to the coronavirus as an “epic disaster” and insisted that the Obama administration would have made more effective decisions to control the outbreak.
“We would have had competent professional people. We would have done what we needed to do early,” he said.
“We would have had someone like Ron Klain in charge of it, not the confederacy of dunces that we see running around the West Wing,” Mr Schmidt added.
The analyst withdrew from the GOP in 2018 over one of Mr Trump’s policies on immigration. He has hit out on numerous occasions over Mr Trump’s handling of the public health crisis.

White House adviser Jared Kushner called the government’s response “a great success story” in an interview with Fox News.
“We’re on the other side of the medical aspect of this, and I think that we’ve achieved all the different milestones that are needed. The federal government rose to the challenge, and this is a great success story,” he said.
More than 1,350,000 people across the US have been infected with the novel coronavirus and over 80,000 people have died from the disease as of Tuesday, according to data from the Johns Hopkins University.
