I don't recall a White House Press Secretary admitting to a falsehood in such a manner before. Sure, it's better than Nixon's man (Ron Ziegler) who lied to Congress but still, by any standard, this was embarrassing. The Mueller report not only exposed her for two blatant lies, it also details how her "slip of the tongue" excuse was, in itself, another lie. She was reading from a prepared statement when she said that countless members of the FBI rank and file had expressed a loss of confidence in Comey... and she also repeated this claim more than once. That is not a slip of the tongue or a mistake. That is preparing a lie and repeating it. Her actions were premeditated and her excuse was lame. She lied and then refused to take ownership of it when busted.
Now, putting that aside for a moment... Sarah Huckabee Sanders is being paid an annual salary of $179,700. For what, exactly? Her beauty and charm? It is a fact that she has held fewer press briefings in the last 6 months than any of her previous 13 predecessors held in such a time frame. That is quite a salary for a press secretary who doesn't interface with the press.
