Transcript for President Trump says Michael Flynn was not forthcoming with the vice president
You heard the president defend the national security adviser he just fired, general Michael Flynn, and trump said today, Flynn was not forthcoming with the president, about a conversation he had with the Russians, and more on what he told the FBI and what he didn't. ABC's senior justice correspondent, Pierre Thomas with what he has just learned. Reporter: Tonight, justice department attorneys are intensely reviewing why former national security advisor Michael Flynn made misleading statements to the white house about his conversation with Russia's ambassador to the U.S. And whether he broke any laws in the process. Sources familiar with the case tell ABC news Flynn was less than entirely forthcoming in an interview with the FBI in the days just after the inauguration, but apparently did not cross the threshold of intentional lying. Today, president trump continued to praise the man he fired. Mike Flynn is a fine person, and I asked for his resignation. He respectfully gave it. Reporter: Flynn came under scrutiny in the intelligence community after white house officials, including vice president-elect Mike pence saying S saying repeatedly, he did not discuss sanctions with the Russian ambassador. The FBI and intelligence community knew otherwise because they had recorded the conversation. In a dramatic move, justice department officials told white house officials that Flynn had misled them and some were concerned he could be blackmailed by the Russians. The white house even as it criticized Flynn for misleading officials there, has argued that Flynn broke no laws. And it's clear the president continues to share that view. He was just doing his job. The thing is he didn't tell our vice president properly and then he said he didn't remember. So either way it wasn't very satisfactory to me. Reporter: Trump even going so far today to say, "He was fine. With Flynn talking to the Russians about sanctions." It certainly would have been okay with me if he did it. I would have directed him to do it if I thought he wasn't doing it. I didn't direct him, but I would have directed him because that's his job." Pierre Thomas with us live from our Washington bureau, and sources telling ABC Flynn was less than forthcoming, and they haven't found an intent to deceive, so he is less likely to face criminal charges here? Reporter: The Flynn investigation and review could take more time to locomplete, but our sources are saying that proving someone intentionally lied is a high bar.
