Washington (CNN) House Judiciary Chairman Jerry Nadler on Friday sent his latest offer Attorney General William Barr to try to reach an agreement in his effort to obtain the unredacted special counsel report and the underlying evidence before Nadler moves forward with holding the attorney general in contempt of Congress.

Nadler sent Barr a new letter proposing that the committee could work with the Justice Department to prioritize which investigative materials it turns over to Congress, specifically citing witness interviews and the contemporaneous notes provided by witnesses that were cited in the special counsel Robert Mueller's report . Nadler wrote that he was "willing to prioritize a specific, defined set of underlying investigative and evidentiary materials for immediate production."

But Nadler's letter does not budge on Democrats' insistence that the Justice Department allow Congress to view grand jury material that's redacted in the report, which Barr has argued he's not allowed by law to provide.

Nadler set a deadline of 9 a.m. ET Monday for Barr to respond and said he would move to contempt proceedings if the attorney general does not comply.

"The Committee is prepared to make every realistic effort to reach an accommodation with the Department," Nadler wrote in the letter, which was obtained by CNN. "But if the Department persists in its baseless refusal to comply with a validly issued subpoena, the Committee will move to contempt proceedings and seek further legal recourse."
