(CNN) The House Judiciary Committee and Justice Department traded letters Tuesday in an effort to kickstart negotiations for Congress to obtain documents from special counsel Robert Mueller's report, but the efforts did not appear to halt a looming vote next week to hold Attorney General William Barr in contempt of Congress.

The House panel and Justice Department still appear to be at loggerheads even after House Judiciary Chairman Jerry Nadler wrote the department and White House late last month to say he was open to limiting the committee's subpoena for the unredacted Mueller report and underlying materials to a smaller subset of documents.

But Nadler on Tuesday evening sent a new letter to the Justice Department rejecting its request to resume negotiations on the committee's subpoena on the condition that the House would delay the contempt vote scheduled for June 11.

"We urge you to return to the accommodation process without conditions," Nadler wrote. "We are ready to begin negotiating immediately."

Nadler's letter came after the Justice Department wrote to Nadler earlier Tuesday saying it could work with the committee to produce a limited set of documents. The Justice Department wrote that it was hoping for a similar concession with the Judiciary Committee that it worked out with the House Intelligence Committee for access to a set of a dozen documents related to Mueller's counterintelligence work.
