The public and members of Congress will be in the dark for at least one more day on Special Counsel Robert Muellers investigation into Russian interference in the 2016 election.

Congress has been informed by the Justice Department that Attorney General William Barr would not provide findings to lawmakers until at least Sunday, officials at Justice and on Capitol Hill confirmed.

The delay is prolonging rampant speculation about what might be in Mueller’s report and fueling Democrats’ increasingly urgent pleas to release the entire document.

In a letter to lawmakers released Saturday, Nancy Pelosi dismissed Barr’s plan to summarize the findings for the relevant committees as “insufficient.”

“Even if DOJ chooses not to prosecute additional individuals, the underlying findings must be provided to Congress and the American people,” Pelosi wrote.

“We are insisting that any briefings to any committees be unclassified so that members can speak freely about every aspect of the report and not be confined to what DOJ chooses to release publicly,” she continued.

Congress is still investigating allegations of obstruction of justice and abuse of power on the president’s part.

“It’s the end of the beginning, it’s not the beginning of the end,” said Sen. Chris Coons, a member of the Senate Judiciary Committee. “It’s important to remember that whatever is concluded by Robert Mueller doesn’t mean that the president and his core team are free of legal jeopardy from these other proceedings. And it’s important to remember that the Congress has a different scope of charge and responsibility than Special Counsel Mueller.”
