The Senate committee's investigation into Russian Federation began in January and is still in its early stages.
Dent is one of the first Republican voices to openly advocate moving the Russian Federation investigation out of the House Intelligence Committee's hands.
"It's safe to say that our staff is now working through thousands of raw intelligence and analytic products", Burr said.
Warner and Burr did disagree slightly, with Warner alluding to some difficulties getting particular documents from intelligence agencies, and Burr defending them.
"We would be insane to dry to draw conclusions from where we are in the investigation", Burr said at a joint news conference with Senator Mark Warner, the top Democrat on the intelligence panel. The only person on that list publicly identified so far is senior White House adviser Jared Kushner, the chairman said.
Burr said the committee would not release names of people who would be interviewed, nor ask them to come before the committee until the "appropriate time".
The show of bipartisanship provided a stark contrast to the feud raging in the House. And now Yates's testimony - and that of everyone else the House Intelligence Committee was planning to interview in the weeks ahead - is on indefinite hold, after Nunes told reporters Tuesday that he would not be scheduling any additional interviews or depositions until after the committee meets with Comey and Rogers.
"All of our meetings this week are canceled, which I've never seen in four years on the committee", Rep. Jim Himes (D-Conn.) said. "Those were regular oversight meetings".
Leading members of the Senate Intelligence Committee confirmed on Wednesday that seven staff members were working on its own inquiry, which is due to host its first public hearing on Thursday. Both "had nothing to do with the [Russia] investigation", Himes said.
Nunes and committee Democrats spent the day disputing assertions made by the other side regarding their investigation's process.
"A new world has emerged in the past years. I don't see any harm being done". Richard Burr, R-N.C. and the committee's Vice Chairman Sen.
Ford recalls 230000 cars over potential engine fires
In October, NHTSA opened a preliminary investigation into 440,000 Ford 2011-2013 Edge SUVs over door latch warning light issues. Ford says it is aware of 29 reports of fire associated with the issue in both the United States and Canada, but no injuries.
Democrats - and some Republicans - have argued that the stalemate indicates the need for an independent commission or a select committee to investigate the matter.
But Republicans in the Senate have thrown their weight behind Burr and Warner's comparatively staid, closed-door investigation.
"There's no need to entertain the possibility of an independent investigator or special commission until after our Intelligence Committee and the Federal Bureau of Investigation complete their work", Sen.
"There are a lot of stories", Warner said.
Lankford sits on the intelligence panel.
The Senate committee's investigation is part of its routine oversight function, just on a bigger scale, he said.
"The House is paralyzed on this thing", Rep. Charlie Dent, R-Pa., said in an interview.
"We are not asking the House to play any role in our investigation and we are not going to play any role in its investigation", Burr said. "Let us go a little deeper into this before you ask us to write the conclusions", Burr said.
Democrats have questioned Nunes's impartiality by noting that he served on the executive committee of Trump's transition team.
The deepening controversy has effectively stalled the work of the committee, which was due to privately meet Federal Bureau of Investigation director James Comey and Michael Rogers, head of the National Security Agency on Tuesday.
"I've got a job in the United States Senate and I take that job extremely seriously and it overrides any personal beliefs that I have or loyalties I may have", he said. "I think that's the only committee that's going to be able to bring us a report at this point".
