“but actual charges will be attempted for obstruction of justice.”
He cannot obstruct himself. He can fire the AG at will. He can direct the AG to start or stop an investigation. He can even direct precisely how to conduct it. He can pardon anyone convicted of a federal crime with no limits.
So how can he obstruct himself?
And I agree, if he talks to the FBI, they will say he lied. But they cannot charge him with it.
Yes, the obstruction charges are ridiculous, but there are enough countering opinions on that matter to enable a politically dirty judiciary to try it.
Sure, it will go nowhere, but that’s not the point. The point is to damage the president and give cover to impeachment-minded ‘rats.
