Story highlights The dossier has become an explosive political issue

Feinstein's decision to release transcript was made without the support of the panel's Republican chairman

Washington (CNN) The top Democrat on the Senate Intelligence Committee said Wednesday he is committed to working in a bipartisan way on the Russia probe after a highly public falling out between Republicans and Democrats on the Senate Judiciary Committee.

Sen. Mark Warner of Virginia was speaking to CNN's "New Day" the day after Sen. Dianne Feinstein unilaterally released the Senate Judiciary Committee's transcript of its closed-door interview with Fusion GPS' Glenn Simpson. Fusion paid a former British intelligence officer to compile an opposition research dossier on President Donald Trump, and it includes unverified allegations that the Russian government has compromising personal and financial information about the President.

The California Democrat's decision was made without the support of the panel's Republican chairman, Iowa Sen. Chuck Grassley, who had argued the committee needed to temporarily protect certain information while an investigation was ongoing.

"The one thing I do know from the Senate Intelligence Committee, we have had our bumps, but we are still working through this in a bipartisan way, we are going to follow the facts wherever they lead, and we have made great progress," Warner said. He added that the judiciary panel "will have to find their own way through."

Grassley said last week that releasing the committee's interview with Simpson, Fusion's co-founder, would "taint" the memory of other witnesses and impact the ongoing investigation. But Feinstein said Tuesday that the "American people deserve the opportunity to see what (Simpson) said and judge for themselves."
