The X accounts of several prominent journalists and leftist pundits were suspended from the site, formerly known as Twitter, on Tuesday morning with no clear explanation.

The suspensions affected several journalists and commentators, including Texas Observer journalist Steven Monacelli, Ken Klippensten of The Intercept, podcaster Rob Rousseau, and Alan MacLeod of MintPress News. The landing page for their accounts says it’s been suspended, but does not give any explanation as to why. A message on the profiles simply states “X suspends accounts which violate the X rules.”
