I watch - habitually - the 6:30 newscasts of all 4 networks on weekdays (NBC,ABC,CBS and PBS) and  while they cover the storms and fires more or less accurately, when it comes to politics, they're almost the same. In sleaziness, NBC is far ahead of the others. Full of innuendos, baseless ad hominem attacks, sensational allegations of fictional, unproven events is their mantra.
Nothing defensible there.
