Special Counsel is appointed in part to prevent bias or the appearance of bias in the investigation, isn't it? This is an important distinction, as Congress itself definitely has a political agenda in nearly everything it says or does.

With that being said, Trump is a stain on our country and deserves to be behind bars, but I wanted to highlight the reason that testifying before a Special Counsel and testifying directly to Congress are very different for a current President. (Which Trump definitely is not.)
