It has been answered because Trump was not inaugurated President for a second term in 2021.
In 2020 the administration was dealing with a new pandemic virus that nobody knew much about at the time. Certainly no heads of state were qualified to know exactly how to handle it, so they were all dependent on supposedly medical experts to advise them. Fauci and his team were the No. 1 'experts' to advise then President Trump.
When President Trump was urging states to start opening back up, the left wing looney governors refused to do so and devastated especially small businesses. Those who did reopen more quickly, i.e. South Dakota, Texas, Florida, etc. had far fewer side effects from COVID than did those Democrat controlled states who used Fauci's incompetent advice as their justification.
Once Fauci's incompetence and/or dishonesty became apparent to us all, I'm sure President Trump would have fired Fauci. Unfortunately he was already out of office and the current administration doesn't care about competence in anything.
