Senate Intelligence Committee Chairman Richard Burr (R-NC), said Thursday, that President Trump’s former national security adviser Michael Flynn was not complying with the subpoena the committee issued for their investigation into the ties between Trump’s campaign and Russian election interference.

Later, Burr walked back the statement. “I may have been premature,” Burr explained. “There may be a day or two left.”

In April, the committee requested documents from Flynn, Trump’s former foreign policy adviser Carter Page, informal adviser Roger Stone and former campaign chairman Paul Manafort. The committee asked the men for various information.

On the communication front, they were asked to list any meetings they had with Russians, provide all records of communication with Russians and list any knowledge they had about meetings between any Trump campaign aides and Russians. The timeframe for reporting was to begin the day Trump announced his candidacy and end at his inauguration.

On the financial side, the senators wanted details about personal financial assets or real estate holding that had a tie to Russia.

Only two responses were received – Page and an unidentified individual. Flynn’s non-compliance resulted in a subpoena.

The emoluments clause of the Constitution strictly prohibits retired military officers from taking payments from foreign governments without advanced permission from the secretary of State and the secretary of the Army.

Flynn, a retired military officer, was paid $45,000 from the Kremlin television network RT to attend a celebration where he was seated next to Russian President Vladimir Putin, in December 2015. He also received money for speeches he delivered to the Russian firms Kaspersky and Volga Dnepr.

Rep. Elijah Cummings, ranking member of the House Oversight Committee, released Flynn’s January 2016 application for renewal of his security clearance. The document does not include any information about his payment from RT or the Russian firms.

Flynn’s lawyers claimed that he briefed the Defense Intelligence Agency “extensively” both before and after the December 2015 trip to Russia.
