No US judge has ever denied a lawful body's subpoena to be "appealed". You'd think Comey would know that and he probably did but didn't think the House committee could get a decision this fast. So the Rats can't save ya Slippery Jim...you'll testify Friday, in secret, where you can't avoid questions by claiming your lies are "classified" because everybody in the room will still have a security clearance and you don't.
Failed attempts such as this to vilify Trump’s critics in no manner undermines the legitimacy of that appropriate and warranted criticism.
I believe you are mistaken. No one is taking away anyone's ability to criticize anyone. The committee wanted Comey to testify on his handling of Clinton. He tried to refuse the subpoena. A judge has ruled that Comey can not refuse and since he will be testifying in closed session he will not be able to withhold answers on the grounds it is classified.
As to what you believe is legitimate and warranted criticism may be debatable at best.
Not so fast sunshine. Comey has agreed to drop his appeal on certain stipulations:
1. The House Committee must provide a transcript of his testimony to Comey within 24 hours of his testimony;
2. Comey will be free to make public any part of the transcript that he sees fit to disclose.
So the hearing will be in private, but it will not be discussing anything that cannot be made public within 24 hours.
Here's a clue dipshit. And this is the real reason why the whole Hillary email investigation was nothing more than a partisan witch hunt. Email is never used to discuss really sensitive matters of national security. And Clinton's server was never hacked, unlike most government servers which are hacked daily.
To pretend that Clinton's private email server just came to light right before the election is no accident either, because Republicans KNEW about that server from day one. It wasn't hidden. Clinton asked the advice of outgoing Republican SS, Colin Powell on how to handle the volume of email she would have as SS, given that government servers limited staff to 25 gb of storage each, regardless of what their position. Powell told her to use a private server, which is what the Bush Administration had done. They had a private server in the White House throughout W's term, and nothing on it was turned over at the end of his Presidency.
Since Bill Clinton already had his own private server at home, which he had set with security consultants so it was a no-brainer to use that server. This was a well secured server that was set up for the worldwide use of a former 2-term President of the United States, not the server for your cousin's dry cleaning business that your middle school nephew set up after school.
Republicans knew about it because after she left office, they passed a law saying that the SS MUST use government secured email only for government business. In interviews they talked about how Hillary Clinton used a private server for her emails, and how this was meant to put a stop to this sort of thing.
Notice how the Trump Administration, which also has a private server in the White House, is trying to pretend that Ivanka Trump's use of a private server for government business isn't illegal, and that her sharing of a domain with someone who didn't have top secret security clearance isn't a HUGE legal problem for her. Lock her up!!
