And a muddled White House response, including a problematic presidential tweet, has left some Trump confidants worried that the president is not being well-served by his legal team and believing his lawyers have painted a too-rosy picture of the president's potential plight.
If anything, the report that Trump learned about Flynn's lies from McGahn could help him.
Mr Trump questioned the direction of the federal law enforcement agency and wrote that the FBI's reputation was "in Tatters - worst in History!"
Cable news has been filled with speculation ever since. "The case for immunity has its adherents, but they based their position largely on the consideration that a president subject to prosecution would be unable to perform the duties of the office, a result that they see as constitutionally intolerable".
Trump on Monday also offered a strong endorsement of Roy Moore, the Republican Senate candidate in Alabama embroiled in accusations that he had inappropriate sexual relations with underage girls.
This supports the idea that when Trump fired Comey, it was with the intention to cover up wrongdoing. The White House is considering reviewing how some tweets, particularly related to the Russia probe, get posted. Dowd also claimed he is the one who drafted the tweet.
And Peter Strzok's texts are "perhaps the most significant evidence of anti-Trump bias uncovered so far on the Mueller team", the Daily Caller noted. Comey has said Clinton did not lie to the FBI during her interview. Wray did send a message to the staff yesterday-not mentioning the president-saying he is "inspired by example after example of professionalism and dedication to justice demonstrated around the bureau".
The former judge said he was grateful for Trump's endorsement.
Trump has taken that counsel to heart, telling two close allies over the weekend that he believed he was in the clear and that Mueller's team wouldn't unveil any further charges, according to the advisers who discussed the private conversations under the conditions of anonymity.
He then added: "Many people in our Country are asking what the 'Justice' Department is going to do about the fact that totally Crooked Hillary, AFTER receiving a subpoena from the United States Congress, deleted and 'acid washed' 33,000 Emails?". That suggests the president may not have known the details about Flynn's FBI interview, he said.
The tweet provoked a firestorm of reaction, particularly in light of former FBI director James Comey's assertion under oath that Trump asked him to drop the investigation into Flynn's conduct. And all who purport to care about American credibility must stop pooh-poohing the underlying behavior here at issue. "He could have pardoned Flynn, which is the ultimate interference by a president of a criminal investigation. So, I just think they're making a mountain out of a molehill".
Famed legal scholar Alan Dershowitz, of Harvard University, expressed the same view on "Fox and Friends" on Monday.
That was news because it was the first time Trump indicated he knew Flynn lied to the FBI.
"You cannot charge a president with obstruction of justice for exercising his constitutional power ..."
"I had to fire General Flynn because he lied to the Vice President and the FBI". After secretly "reassuring" Russia that it need not worry about facing consequences, the Trump administration did not deliver.
Pence, who served as head of Trump's transition, has not publicly commented on Flynn's plea.
Papadopoulos cultivated Russian contacts during the campaign and tried to arrange a Trump trip to Russia or a meeting with Russian President Vladimir Putin.
