Not for legal process, no. I agree.
I find it troubling because the committee is lauding a guy who is a liar and a snake. None of them expressed the least bit of "taint" to him leaking, or to him back-stabbing the president, e.g., not confronting him with his belief to have been asked to obstruct justice - he was so rattled he NEVER took it up with anybody who could get back to Trump.
Some of them were troubled by what Trump was alleged to have done, but NONE of them was troubled by Comey. That speaks to their personal integrity, their tolerance of perfidy, their own inability to stand up for the truth, and other issues that are wholly political.
Our government is nearly totally corrupt, so I suppose it makes sense none of them have trouble with corruption, until it stinks so bad they have to distance themselves from that little tainted spot.
I believe Comey chose that committee to testify because it was known that it would be rigged. I doubt that he will testify in the House Oversight Committee when given the opportunity.
