2016 RNC Delegate: Trump Directed Change To Party Platform On Ukraine Support
President Trump may have been involved with a change to the Republican Party campaign platform last year that watered down support for U.S. assistance to Ukraine, according to new information from someone who was involved.
Diana Denman, a Republican delegate who supported arming U.S. allies in Ukraine, has told people that Trump aide J.D. Gordon said at the Republican Convention in 2016 that Trump directed him to support weakening that position in the official platform.
Recall that this was the only proposed platform policy the Trump people saw fit to adjust. After running a “populist” campaign that was credited by the more gullible members of the Beltway media herd for rejecting GOP orthodoxy and goring Republican sacred cows left and right, when the so-called insurgents seized control, the sole alteration they requested just coincidentally was designed to make Putin’s life easier.
Trump’s flunky Gordon now denies he told Denman that the platform change request came from Trump. Uh huh.
I’ve always thought this platform change smelled fishier than a scratch-and-dent Chicken of the Sea warehouse.
