Ryan has encouraged Gowdy, a former federal prosecutor and one of House Republicans' most experienced investigators, to help calm tensions between Nunes and the Justice Department.
The Justice Department says it will offer a third classified briefing for lawmakers next week on the FBI's handling of its Russian Federation probe.
"Today for the first time I was hearing colleagues say, 'Well, Speaker Ryan won't stand with us in this fight over the essentials of our democracy, not weaponizing the intelligence community against the presidential campaign".
On Thursday, after the Justice Department offered the new briefing, Burr said "I have a hard time figuring out what else they could produce".
"I don't know the technical answer to that question, but I think obviously the answer is he shouldn't", Ryan told reporters.
Ryan is retiring at the end of the congressional term.
The Justice Department's decision to provide multiple briefings on the subject is a significant departure from its initial stance after receiving Nunes's subpoena. Trump tweeted on Monday.
American diplomats fall ill in China after hearing odd noises
At least two diplomats have recently been evacuated from China with the number possibly to rise soon, the New York Times reports . In response, it downsized the US diplomatic staff in Havana and prohibited families from joining the diplomats who stayed.
Trump claimed Monday that he has "the absolute right to pardon myself", as Special Counsel Robert Mueller's year-long probe continues into possible collusion between Russian Federation and Trump's 2016 election campaign, as well as possible obstruction of justice.
Rep. Mark Meadows, R-N.C., who has floated the possibility of impeaching Deputy Attorney General Rod Rosenstein, who oversees Mueller's probe, declined to comment on Ryan's take until after he had spoken directly with the speaker. The only Republican briefed on the intelligence who has yet to break from Trump is Rep. Devin Nunes, the House Intelligence chairman who has demanded more documents as part of his investigation.
Giuliani on Wednesday said Mueller's office was trying to frame the president in its investigation. "But what we were asking for and what we require and what we expect were the corroborating documents of that oral briefing".
Ryan described as accurate remarks made by Rep. Trey Gowdy, R-S.C., chairman of the House Oversight Committee, who attended the earlier briefing and told Fox News that "the Federal Bureau of Investigation did exactly what my fellow citizens would want them to do" in investigating the allegations. But no members asked to view them.
"You know I run in the more conservative circles of the House and I have never up until this point heard a single person talk about removing Speaker Ryan from the speakership", Gaetz told Fox Business Network in an interview Wednesday.
The department originally denied Congress access to any of the documents, citing national security concerns. Thirteen are registered Democrats; four are either unaffiliated or their affiliation is unknown, according to the Washington Post. Previously, she worked at the Associated Press for more than 17 years, starting in the Los Angeles bureau and going on to cover the White House and Congress.
