A new bipartisan report from the Senate Intelligence Committee on Russia's election interference is expected to be released next week, lawmakers said Friday.

The third installment of the panel's five-part investigation into Russia's election interference efforts is set to focus on how the Obama administration responded to hacking and disinformation operations directed by the Kremlin.

Burr said the delay was a result of the intelligence community needing to review and declassify the findings, and to include majority and minority views in the report.

He blamed the intelligence community's declassification process for slowing the release of both the third and fourth volumes of the investigation.

“Both of them, they have been done for months now. I do worry that a declassification process that has always been legitimate, I start to have increasing questions about whether it’s being politicized,” Warner said.
