A former top vaccine official removed from his post last month alleged in a whistleblower complaint on Tuesday that he was reassigned to a less prestigious role because he tried to “prioritize science and safety over political expediency” and raised health concerns over a drug repeatedly pushed by President Trump as a possible cure for coronavirus.

The coronavirus response being spearheaded by President Trump’s son-in-law, Jared Kushner, has relied in part on volunteers from consulting and private equity firms with little expertise in the tasks to which they were assigned, exacerbating chronic problems in obtaining supplies for hospitals and other needs, according to numerous government officials and a volunteer involved in the effort.
