Update on April 3. This opinion piece by Michele Goldberg of the NY Times makes the point that Kushner’s role is not only unusual, but dangerous. See: Jared Kushner Is Going to Get Us All Killed. Trump’s son-in-law has no business running the coronavirus response.

Update on April 2. From the NYTimes: Kushner Puts Himself in Middle of White House’s Chaotic Coronavirus Response. President Trump’s son-in-law has become a central player in the administration’s effort to curb the pandemic. But critics say he is part of the problem.
From Politico this rather surprising account of a new, private-sector group at work at FEMA: Behind the scenes, Kushner takes charge of coronavirus response. Trump’s son-in-law sets up shop at FEMA as his portfolio balloons to include manufacturing, supplies and long-term planning.
Two things you can’t argue with – success and failure. The Feds’ response has generally not been very successful; apparently Kushner, et al., have been. In wartime, you have to go with what works. Leave the handwringing about what might – or might not – be unethical until after the battle’s won.
