Michael Flynn sent a text to a business partner as President Donald Trump was delivering his inaugural address last January that a joint plan between Russian Federation and Flynn's business allies to build nuclear power plants in the Middle East was "good to go".
Quoting a confidential informant, Rep. Elijah Cummings, the top Democrat on the House Oversight and Government Reform Committee, wrote that Alex Copson, managing partner of ACU Strategic Partners, told the informant that Flynn would see that the sanctions on Moscow were "ripped up".
'Our committee has credible allegations that President Trump's National Security Advisor sought to manipulate the course of worldwide nuclear policy for the financial gain of his former business partners, ' wrote Cummings, Politico reported in a story on the letter.
Mr Cummings wrote that he delayed releasing the letter at the request of Justice Department special counsel Robert Mueller until his team had "completed certain investigative steps".
But in his interview with the Federal Bureau of Investigation last January, 24, according to the Justice Department documents, Flynn lied when he said he did not ask Kislyak "to refrain from escalating the situation in response to sanctions that the United States had imposed against Russian Federation".
One of President Donald Trump's former aides texted an associate that U.S. sanctions against Russian Federation would be "ripped up", a lawmaker says.
Flynn had texted Copson with the same message - that the nuclear reaction project was "good to go" - from his place on the dais outside the Capitol 10 minutes into Trump's inaugural address, the whistleblower told Cummings.
Cummings said the individual contacted his office and authorized him to make his account, but not his name, public.
Flynn had worked as a consultant for ACU Strategic Partners, the group pushing the proposed nuclear deal, in 2015 and 2016. That agreement made no mention of Flynn's consulting work for companies pursuing a controversial nuclear power project in the Middle East that involved Russian participation. "I am going to celebrate today", and added, according to the whistleblower: "This is going to make a lot of very wealthy people".
According to the whistleblower, Copson said, "Mike has been putting everything in place for us".
Cummings has argued that the Flynn plea deal should alleviate that concern. He and Cummings jointly exposed details that Flynn had lied on his security clearance forms earlier this year, though Chaffetz later backed off the inquiry despite the Democratic demands. "I have spoken to this whistleblower, and I find this person to be authentic, credible, and reliable", Cummings wrote.
Neither Gowdy nor Flynn's attorney, Robert Kelner, responded immediately to a request for comment. Cummings said he believes Republican leaders of the Oversight Committee should approve a subpoena so they can "pursue these allegations against General Flynn in a responsible way".
Cummings did not identify the whistleblower.
