Separately, the New York Times reported on Friday that Mr Trump told Russian officials at a White House meeting last week that firing Mr Comey relieved "great pressure" that the president was facing from the ongoing probe into Russia and the election.
Trump fired Flynn in February after it became clear that he had falsely characterized the nature of phone conversations with Kislyak in late December - after the November 8 election and just after the Obama administration announced new sanctions on Russian Federation.
In December 2016, the Department of Justice (DOJ) opened up an investigation into Flynn for his lobbying on behalf of the Turkish government despite not registering as a foreign agent.
He was also said to have told Russian Foreign Minister Sergey Lavrov and Russian Ambassador to the US Sergey Kislyak that "I'm not under investigation".
On Thursday, Trump lashed out over the appointment of former Federal Bureau of Investigation director Robert Mueller as the special counsel to probe Trump-Russia ties, saying that it "divides country".
That would surely include Trump's firing last week of FBI Director James Comey. On May 9, he fired FBI Director James Comey for his alleged incompetence, but critics said that Trump was actually getting rid of him because he was investigating the president's ties to Russian Federation and wanted more money to do so. Trump said of the investigation swirling around his presidency.
"Once again, the real story is that our national security has been undermined by the leaking of private and highly classified conversations", he said.
Well, according to a new report from The Washington Post, people familiar with the investigation say that a current senior administration official has been identified as a person of interest in the probe.
Citing a different source, the Daily Beast's report states Flynn would have preferred to have been nominated as Director of National Intelligence or Director of the Central Intelligence Agency. The official added "General Flynn was the person closest to [Trump] on national-security matters".
Trump personally denied any Russian collusion during a press conference Thursday.
Asked if he urged Mr Comey at a February meeting to drop his probe of the Russian Federation connections of Mr Trump's national security adviser, Michael Flynn, the president said: "No. No". The document relaying this account was reportedly based on notes taken during the meeting. But for someone who premised a campaign - and a presidency - on his unblinking ability to not only pick the best and brightest but then to find ways to make them even more successful, Trump's misjudgment of Flynn seems like a major black mark. Director James Comey on May 9, the White House has ducked, dodged, and repeatedly revised its rationale.
