Another Trump adviser has significantly changed his story about the GOP's dramatic shift on Ukraine

The Trump campaign's national-security policy representative for the Republican National Convention, J.D. Gordon, told CNN on Thursday that he pushed to alter an amendment to the GOP's draft policy on Ukraine at the Republican National Convention last year to further align it with President Donald Trump's views.

Gordon's remarks represent a dramatic shift from previous comments, and they come as Attorney General Jeff Sessions faces intense scrutiny over two previously undisclosed meetings with Russia's ambassador to the US — one of which was timed to the convention.

In January, Gordon told Business Insider that he "never left" his "assigned side table" nor spoke publicly at the GOP national security subcommittee meeting, where the amendment — which originally called for "providing lethal defense weapons" to the Ukrainian army to fend off Russian-backed separatists — was read aloud, debated, and ultimately watered down to "providing appropriate assistance" to Ukraine.

Paul Manafort was Trump's campaign manager from April through August of 2016. He served as a top adviser to a pro-Russian political party in Ukraine from 2004 to 2012 and helped the Russia-friendly strongman Viktor Yanukovych win the Ukrainian presidency in 2010.

Manafort and Trump later denied having anything to do with softening the language of the GOP's platform on Ukraine.

"I wasn't involved in that," Trump said in an interview with ABC after the convention. "Honestly, I was not involved."

But he said his supporters were. "They softened it, I heard, but I was not involved," he said.

Authority and responsibility to shape the GOP platform

Gordon told Business Insider in an email Friday that there is "nothing different in what I told you and Jim," referring to Acosta. "His tweet was an issue of semantics, which I've shared with him just now to ensure we're all on the same page."

he RNC & Trump Campaign intent @ GOP Platform Week was to 'prevent' adding any glaring contradictions to the draft GOP Platform we brought to Cleveland and previously stated Trump positions," Gordon added. "This included the notion that arming Ukraine would have been contrary to the goal of improved relations with Russia."

"The RNC and Nominee's Campaign have the authority and responsibility to shape the GOP Platform," Gordon said. "Delegates who have their amendments defeated in part and in whole should understand the process."

Gordon said in January that neither Trump nor Manafort were involved in the platform change, however. He also claimed his only role as a Trump campaign representative at GOP Committee Week — which took place in the week prior to the RNC's kickoff — was "

USA Today reported Thursday that Gordon and another former Trump campaign adviser, Carter Page, met with Russia's ambassador to the US, Sergey Kislyak, at the RNC. Gordon said he considered it "an informal conversation just like my interactions with dozens of other ambassadors and senior diplomats in Cleveland."

According to CNN, Gordon said he and Kislyak discussed the Trump campaign's "goal to forge a better US relationship with Russia."

Gordon insisted in January that his only role as a Trump campaign representative at GOP Committee Week — which took place in the week prior to the RNC's kickoff — was "

Diana Denman, the GOP delegate who proposed amending the Ukraine platform to include the "lethal weapons" language, contradicted Gordon's version of events in an interview with Business Insider in January. She said that Gordon and another Trump campaign representative asked the co-chairmen of the subcommittee to table the amendment after she read it aloud.

"Two men sitting over to the side of the room — I had no idea who they were, but later found out they were Trump representatives — jumped up and tore over to get behind the three co-chairmen," she said.

Gordon then left the room to make a phone call, Denman said. Equal parts confused and angry over her proposal being scuttled, Denman said she confronted Gordon about who he was calling.

"I'm calling New York," Gordon

"I work for Mr. Trump and I have to clear it," she recalled him saying, apparently in reference to the amendment.

Gordon said in an email at the time that Denman "sought to significantly elevate the Ukraine-Russia issue beyond the already strong position of RNC and Trump campaign," so the language had to be watered down.

"It was controversial if you hold Donald Trump's express views on Russia, but it wasn't controversial with regard to GOP orthodoxy on the issue," the committee member said."This change definitely came from Trump staffers — not from RNC staffers."

The White House did not immediately respond to requests for comment on Friday.
