How much do they hate Trump? Do you not think this came from Inhofe’s staff? Or whomever he dined with?
If he’s dining with a staffer then Inhofe knew it was being recorded. If he was dining with a staffer then the staffer should have the integrity to realize who is on the phone and what they’re talking about.
However, if Inhofe was dining with “someone from the other side” why in the world would put it on speakerphone. Leak or no leak, this is on Inhofe.
