1. SOUNDBITE (English) Sen. Richard Burr, (R) North Carolina:
"General Flynn's lawyer said that he would not honor the subpoena and that's not a surprise to the committee. But we'll figure out on General Flynn what the next step, if any, is. But we're continuing on with a lot of interviews and through those interviews it leads us to additional document requests and additional individuals we'd like to talk to."
2. SOUNDBITE (English) Sen. Richard Burr, (R) North Carolina:
"Director Comey is a public citizen now. He's not constrained by investigations and we think the most important thing that Director Comey can contribute now is an understanding by the American people of what transpired. We happen to think that an open hearing in front of the intelligence committee is the right way for him to do it since we've worked so closely with him and we respect him so much."
3. SOUNDBITE (English) Sen. Lindsey Graham, (R) South Carolina:
"The shape and the scope of the congressional investigation I think has dramatically changed. I respect the decision. Mueller is a good guy. But one of the big losers here is the public because we're not going to hear from Comey now most likely. I hope we do. I want to hear about the conversation. I want to know the context of it. But now that you have a special counsel, maybe that's off the table."
4. SOUNDBITE (English) Sen. Lindsey Graham, (R) South Carolina:
"I'm disappointed in many ways that the Congress may be taken out of the game now because we're a public venue. I thought Yates and Klapper were good. I thought Sally Yates was an excellent witness. I thought Klapper provided insight to the public that we all need to know, you know. It's our nation here. So hearings like that are probably now off the table, and too bad."
5. SOUNDBITE (English) Sen. Ted Cruz. (R) Texas:
"I don't think appointing a special counsel was necessary. But if one was going to be appointed, I think Bob Mueller is an excellent choice."
6. SOUNDBITE (English) Sen. John McCain, (R) Arizona:
"There is a new revelation almost everyday, like this morning there's a new revelation that there was more communications between the Trump campaign and the Russians in that respect that there is a new revelation every few days."
7. SOUNDBITE (English) Sen. Patrick Toomey, (R): Pennsylvania:
"Well my opinion of Bob Mueller is that he's terrific, completely unimpeachable in all respects and widely recognized as such by everybody. I never really was convinced that this is the best way to go. We have in the past when we've used special prosecutors and special counsels it hasn't always ended well. My view was always that the president should move quickly to get a completely unimpeachable leader of the FBI, preferably a Democrat so that there would be no doubt that that organization is being run by somebody who has no allegiance to Donald Trump."
Senate Republicans have mixed reactions to the surprise announcement that the Justice Department has appointed former FBI Director Robert Mueller as a special counsel to oversee a federal investigation into possible collusion between Russia and the Trump campaign in 2016.
The Justice Department on Wednesday appointed former FBI Director Robert Mueller to lead the investigation. Mueller will have sweeping powers and the authority to prosecute any crimes he uncovers.
Senate Intelligence Committee Chairman Richard Burr who considered the appointment as a good decision said that ousted National Security Adviser Michael Flynn will not honor a subpoena issued by a Senate committee looking into Russia's meddling in the 2016 presidential election. Burr told reporters Thursday that Flynn's lawyer informed the panel he will not abide by a subpoena for private documents.
President Donald Trump lashed out at the appointment of a special counsel to investigate allegations that his campaign collaborated with Russia to sway the 2016 election, tweeting Thursday that it is "the single greatest witch hunt of a politician in American history!"
Reactions from Congress to Mueller's appointment were mainly positive, even though Republicans had dismissed an independent outside investigation as unnecessary and duplicative of what congressional committees already are doing.
Sen. John McCain of Arizona, the Republican chairman of the Armed Services Committee, says it's a "scandal" of Watergate proportions, and the only way to end it is to get out the full truth.
Republicans have largely stood behind Trump in the first months of his presidency as the FBI and congressional investigations into Russia's election meddling intensified. But GOP lawmakers have grown increasingly anxious since Trump fired Comey, who had been leading the bureau's probe - and after Comey associates said he had notes from a meeting in which Trump asked him to shut down the investigation into the Russia ties of former National Security Adviser Michael Flynn.:
