Former national security advisor Susan Rice has accused Donald Trump of failing to properly prepare for a global pandemic despite ample warnings.

Ms Rice, who played a key role in the Obama administration’s response to the Ebola crisis, said her team had briefed incoming Trump officials about the risk of another pandemic during the transition. As part of that effort, her team held an exercise that explored what to do in the case of a global pandemic, she claimed.

“We knew this was a serious and impending risk,” she told CNN. “That’s why under the Obama administration we set up an office for global health security and biodefence. We staffed it with a senior person and made sure they could report directly to the national security advisor and the homeland security advisor. Two years ago that office was dismantled.”

The Trump administration’s decision to disband that office in 2018 has been cited as one reason for the government’s delayed response to the coronavirus outbreak.

Even current Trump officials have said the office had served a useful purpose.

“It would be nice if the office was still there,” Dr Anthony Fauci, the director of the national institute of allergy and infectious diseases at the national institute of health, told Congress last week. “I wouldn’t necessarily characterise it as a mistake (to eliminate the unit). I would say we worked very well with that office.”

Mr Trump has defended his administration’s response by claiming the coronavirus pandemic “blindsided the world” and “came out of nowhere”.

Ms Rice, who was also US ambassador to the United Nations, said that claim was “false.”
