I have watched PBS News Hour as primary TV news since 1973. Greatly appreciated that it was not possible to discern moderators' partisan leanings under Robert McNeil, Jim Lehrer, Gwen Ifill, or Judy Woodruff.
They each let viewers decide on guests' credibility and opinion.
That pattern has dramatically changed with the younger reporters over past couple years. They are each partisan. The show is becoming left-wing.
That has been evidenced in reporting on BLM movement, DC statehood, anti-Semitic BDS movement, and Capitol Hill partisanship.
