A public feud between two right-wing media figures over a stalled government investigation, bad for both men's credibility but pointing at a real transparency question.

• Dan Bongino released a few private text messages from Tucker Carlson to dispute something Carlson said.
• Carlson claims Trump did shut down the investigation, and says he won't fire back by dumping all their texts.
• The bigger issue: if the investigation is still open, where is it, and why hasn't the government's evidence been made public.
• Carlson says the trading of private screenshots is a game he doesn't want to play.

Outlook: The fight is likely to keep fueling pressure to release the underlying evidence rather than settle the personal dispute.
