President Donald Trump’s former national security advisor Micheal Flynn is under fire for failing to disclose payments from the Russian television network RT and two Russian firms Volga-Dnepr Airlines and Kaspersky Government Security Solutions in an ethics form he signed, according to documents released by the White House, reported Reuters.

The files were released after House Oversight and Reform Committee Chairman Rep. Jason Chaffetz, R-Utah, and the panel’s top Democrat, Maryland Rep. Elijah Cummings, requested Flynn’s ethics agreement after his spokesman Price Floyd confirmed that he had not signed an ethics pledge barring him from lobbying on behalf of a foreign government.

In a financial disclosure form released Saturday Flynn listed his former speaking engagements to Russian entities, including the Kremlin-funded RT TV, Volga-Dnepr Airlines and Kaspersky Government Security Solutions under a section titled “sources of compensation exceeding $5,000 in a year.”

But the payments for the speeches were not included in the original ethics form in January which was also released by the White House.

Flynn is under intense scrutiny for his contacts with several Russian officials in a wider investigation into alleged Russian meddling in the 2016 U.S. presidential election that has so far turned up no leads or evidence.

The former Lieutenant General has requested immunity to testify before the intelligence committees of the U.S. Senate and the House of Representatives, his lawyer, Robert Kelner, said. Noting the testimony itself was likely to be anti-climactic.

“No reasonable person who has benefit of the advice from counsel would submit to questioning in such a highly politicized, witch hunt environment without assurances against unfair prosecution,” Kelner said.
