the comments about "fired for lying to VP Pence and the FBI.."

were made by Trump or his lawyer.

Trump said it was tweeted by his attorney and his attorney says he was paraphrasing his other attorney?

It was not done without thinking. It was done intentionally. Because they were "fishing" for comments from the SPO.

Since Flynn was now under the protection of Robert Mueller, all of them knew that Mueller had possession of the FBI recording of Flynn to Kislyak and the Russians. However, they did not know specifically who Flynn may have mentioned in his recording with the Russians? They really need to know if Flynn mentioned Trump and in what context??

It was done with a purpose. However, it appears that they still do not know what is on the FBI recording?

But, Mueller knows.
