Tweets are often impulsive, especially when they emanate from presidential thumbs. Their meaning should not be overburdened. But impulses can expose genuine thoughts, so the particular modifier President Trump deployed to twist the shiv in Attorney General Jeff Sessions was at least suggestive: His chief law-enforcement officer had assumed a “weak position on Hillary Clinton crimes (where are E-mails & DNC server) & Intel leakers!”
Note that Sessions is being upbraided not for taking an unjust position but for taking a “weak” one. Weakness was said to be Reince Priebus’ sin, too. Some reports had the President unimpressed with the dignified, which is to say silent, position Priebus took under foul-mouthed fire from the White House Director of Communications, Anthony Scaramucci (he whose name is a lot like the Italian word for “skirmish,” and who, as of yesterday, is no longer the White House Director of Communications).
