The FBI will not be pursuing charges against President Donald Trump's former national security adviser Michael Flynn, CNN reported tonight, for what he said in interviews dealing with his conversations with Russia's ambassador.

Though there are still unanswered questions about the former administration official's relationship with Russia, which could result in further rebuke, as both the FBI and Congress are looking into it.

For instance, the Pentagon informed lawmakers that there are no records of a 2015 trip that Flynn took to Moscow, where he rubbed elbows with Russian leader Vladimir Putin, according to Politico.

The FBI won't pursue charges against former National Security Adviser Michael Flynn over statements he made about conversations with Russia's ambassador during the transition

Flynn may have also received unconstitutional payments from a foreign government because of this appearance, as the Constitution's Emolument's Clause has been interpreted to apply to retired military officials.

The clause prohibits a person holding public office from benefiting financially from a foreign entity.

Acting Army Secretary Robert Speer confirmed to the chair and ranking member of the House Oversight Committee that Flynn did not document the trip.

In turn, the lawmakers signed onto a letter to the speakers bureau, Leading Authorities, which set up the excursion, asking for information about payments made to the official.

Rep. Jason Chaffetz, the Republican chair of the committee, has also called for an investigation into the leaks plaguing the Trump administration, which the president railed against today from a White House podium.

Chaffetz so far has ignored pleas by his Democratic colleagues to investigate Trump campaign officials' correspondence with Russian intelligence officials, conversations that the New York Times first uncovered this week.

When the president was asked about it today, he skirted the question by bringing up Flynn.

'Can you say whether you are aware that anyone who advised your campaign had contacts with Russia during the course of the election?' one reporter asked.

'Well I told you, Gen. Flynn obviously was dealing. So that’s one person,' the president answered.

The contact in question happened before the president was elected, while Flynn's problematic correspondence took place during the transition.

Flynn had originally told investigators that he didn't discuss sanctions when speaking to Russian Amb. Sergey Kislyak as Trump's incoming national security adviser.

CNN reported that FBI agents then challenged Flynn and then the ex-military official said he didn't remember.

Officials told the news network that they didn't believe Flynn was deliberately misleading them and thus charges wouldn't be pursued.

There is, however, a broader FBI probe into Flynn's Russian dealings.

The national security adviser was asked by the president to resign this week over withholding the content of his conversations with the Russian ambassador from Vice President Mike Pence.
