Michael Flynn, President Donald Trump's former national security adviser, promised to swiftly end United States sanctions against Russian Federation as one of the "first orders of business" for the incoming Trump administration, according to a whistleblower's account detailed in a new letter from Rep. Elijah Cummings (D-Md.), the top Democrat on the House Oversight and Government Reform Committee.
At an inauguration party after the speech, "The whistleblower greeted Mr. Copson.and asked how he was doing", according to an account released by Elijah Cummings, the ranking Democrat on the House committee. Copson was working at the time with Flynn on a project to build nuclear reactors in the Middle East, and Flynn reported in August that he served as an "advisor" to Copson's company between 2015-2016.
Former National Security Advisor Michael Flynn told a former business associate "within minutes" of President Donald Trump being sworn in on Inauguration Day that economic sanctions against Russian Federation would be "ripped up" once Trump gets into office, according to a whistleblower.
The whistleblower, who provided his account to Cummings in June, said he was with Alex Copson, managing partner of ACU Strategic Partners, a key Flynn ally on the nuclear project, on January 20, Inauguration Day.
"And he apparently went on to say Flynn was making sure the sanctions would be "'ripped up' as one of his first orders of business".
"Our committee has credible evidence that President Trump's National Security Advisor sought to manipulate the course of global nuclear policy for the financial gain of his former business partners", wrote Cummings.
ACU was pushing a nuclear project in the Middle East that Flynn is said to have lobbied for while in the White House.
Copson, according to the whistleblower, said Obama's sanctions had "f**ked everything up in my nuclear deal with the sanctions".
Gowdy has not responded to requests from ABC NEWS for comment.
"These grave allegations compel a full, credible, and bipartisan congressional investigation", Cummings wrote in the letter to Gowdy, a South Carolina Republican, which outlines the information provided by the whistle-blower.
"Although this individual was extremely hesitant to come forward - and still fears retaliation - the whistleblower has made a decision to do so now because this individual feels duty bound as a citizen to make this disclosure", he wrote. The whistleblower alleged Copson showed off the text to those around him, calling it "the best day of my life".
The allegations posed new troubles for Flynn, who left the White House last February after barely three weeks and pleaded guilty last week to lying to FBI investigators in the Russian Federation election meddling probe. The whistleblower said during a conversation, Copson described his messages with Flynn and briefly flashed one of the texts, which appeared to have been sent 10 minutes after Trump began speaking.
Reached Wednesday, Flynn's attorney declined to comment. It was pushed by a company that Flynn had advised during the 2016 campaign and transition, seeking to promote a joint venture with Russian Federation to build nuclear power plants in the region. The whistleblower isn't named, but Cummings promised in the letter to share the person's identity with Gowdy if it remains confidential and Gowdy agrees to speak with the whistleblower.
