Donald Trump has stoked speculation that he intends to sack his top immunologist, Dr Anthony Fauci, from the White House coronavirus task force by retweeting a post from a failed Republican congressional candidate that included the hashtag “FireFauci”, although his doing so would surely provoke a major backlash.The White House has denied that the president is firing the top doctor advising the coronavirus response, while blaming Democrats and the media for “ignoring” the virus threats despite reports revealing how Mr Trump repeatedly ignored warnings for several weeks, as early as January.
