Among the jobs eliminated were epidemiologists and other health professionals whose departure left the CDC office in Beijing "a shell of its former self", according to one USA official who worked in China at the time of the drawdown.
Taking to Twitter, Congressperson Greg Steube also said that World Health Organization has acted as China's mouthpiece during the outbreak.
"China tells you numbers", he continued, adding, "I am sure you are not able to tell what China is testing or not testing".
Trump's proposal on Tuesday to ease restrictions by mid-April came as a number of state and local governments have moved in the opposite direction, heeding the advice of public health officials to implement stay-at-home orders and close non-essential businesses to stem the rising number of coronavirus infections.
Mississippi Republican Governor Tate Reeves, who has not ordered business closures or limits on social behaviour, thanked Trump for recognising that the virus has affected states differently and "one size does not fit all".
"He's much more concerned about self-preservation and self-aggrandizement than he is about doing the right thing as a leader in a time of crisis", said O'Brien, who worked as an advisor to Michael R. Bloomberg's now-shuttered campaign for the Democratic presidential nomination.
Trump was asked if he agreed that the WHO showed favouritism and the United States should re-explore its relationship with the Geneva-based United Nations health agency once the dust settles.
The "malign misinformation" refers to recent allegations by Chinese diplomats that the Covid-19 virus did not originate in Wuhan, capital of Hubei province, but that it was brought to China by a team of USA athletes who had come to participate in the 2019 Military World Games that took place between 18 and 27 October in Wuhan. "A lot of people are not happy about it".
Congressperson Steube and Senator Josh Hawley both demanded that World Health Organization and China face consequences for their actions.
Senator Josh Hawley echoed Steube's view and demanded the same. Steube said, "There need to be consequences here". That data will drive the "next phase" of the response to the pandemic, he said.
Tedros had praised China's leadership for its "determination to end the new coronavirus outbreak".
Tedros has been accused of aiding the Chinese "propaganda".
Ghebreyesus had gone to China in January to meet President Xi and a WHO team comprising of worldwide health experts was working in the country. "World Health Organization appreciates the seriousness with which China is taking this outbreak & the transparency authorities have demonstrated", he had said in a tweet after his meeting with Xi.
Subsequently, WHO sent a team of experts to Beijing, Guangzhou and the virus epicentre Wuhan.
The US-China spat came as Trump has termed COVID-19, Chinese virus, which Beijing refuted saying that it amounted stigmatisation. Data shows the USA has the most confirmed cases in the world now at 83,097, according to Worldometer, which tallies from Johns Hopkins University and recent media reports.
