Robert S. Mueller III and House Democrats have not been able to agree on how much of the specialized council's expected congressional testimony would be public and how much would take place privately, according to people who know the case.
The Special Council's office has been negotiating with the House's Court Committee, whose chairman, Rep. Jerrold Nadler (DN.Y.) has been eager to have Mueller witness as soon as possible.
According to people who were familiar with the case, Mueller would like to be conducted privately for any discussion beyond the public content of his report. Democrats will press Mueller into a national television hearing on a variety of issues, including whether he believed President Trump could or should be charged with obstruction if he were not the president and whether Mueller agreed with the Justice Minister William P. Barr's of survey results.
The Secretary-General released an easily edited version of Mueller's 448-page report a month ago, and ever since Democrats have pushed for Mueller to testify.
