Pipophobia 

The fear of becoming a subject of a presidential Twitter post. For politicians, especially members of the president’s party serving in the United States Senate, the fear is existential.
From pipo which means tweet in Latin and the common root, phobia, meaning fear.

Senate Republicans were unjustly thought of as craven lackeys when, if fact, they suffered from acute pipophobia, a condition rendering them small shells of their former selves and too pitiable to be held accountable.
