Is almost literally what happened earlier today, March 9th, 2020. The National Association of Immigration Judges recommended that immigration courts display disease prevention posters in english and several other languages to protect court employees, lawyers, and attendees.
But as odd as it seems for a court to be part of the executive branch, in the case of immigration courts, they are organized under Article II powers (executive powers, thus accountable to the president) rather than article III (judicial powers, thus accountable to the Supreme Court generally on some matters, or the Chief Justice specifically on remaining matters) because the constitution gives authority over immigration and naturalization to the executive, subject to duly passed laws.
As a result, the President has the authority to interfere with immigration courts to the extent not prohibited by law passed by Congress and signed by the President (or passed with veto-override). Apparently the President or his delegates were none too pleased that immigration judges wanted to prevent death and disease and ordered immigration courts to take the posters down:
EOIR has ordered immigration court staff to remove CDC posters designed to slow spread of coronavirus.
No, this is not a parody account.

It’s hard to explain just how heinous and shortsighted this is, but mostly because it is so obviously heinous and shortsighted. To the Trumpists who actually need this explained, I doubt comprehension will ever come.
