Federal law requires Mueller to present Attorney General William Barr with a confidential report upon the completion of his work, but it's ultimately Barr's call on how much of that report is made public.
Yet it seems even Republicans are fed up with the secrecy, as the House voted unanimously Thursday on a resolution demanding the report be made public.
One of Special Counsel Robert Mueller's top prosecutors will soon leave his post, a spokesman said on Thursday, confirming a move likely to add fuel to speculation that the investigation into Russia's role in the 2016 US election is nearing an end.
Four Republicans voted present: Michigan Rep. Justin Amash, Florida Rep. Matt Gaetz, Arizona Rep. Paul Gosar and Kentucky Rep. Thomas Massie.

Weissmann's upcoming departure is the latest sign that Mueller is all but done, NPR said.
The resolution also calls for the report to be sent to Congress.
Weissmann has been a pivotal member of Mueller's team, which has brought charges against 34 people and three companies during a 22-month-old investigation into whether Trump's 2016 campaign conspired with Russian Federation and whether the Republican president unlawfully sought to obstruct the probe. As it is, what happens if Barr decides not to release the report and rumors start appearing in the papers that Mueller told Barr there's probable cause to believe Trump obstructed justice?

"I've said to millions of Americans on television that I support releasing the Mueller report". He defended Barr, saying he "understands the questions, the turmoil this has caused".
Though they voted for the resolution, many Republicans expressed skepticism about the wisdom and likely success of Democrats' quest.
House Democrats are prepared to use subpoena power and other tools at their disposal to force the Justice Department to turn over anything Barr chooses to withhold.
"Those are also going to be things that we are going to have to litigate", Collins said.
