Special counsel Robert Mueller is reportedly ready to release his findings on key components of his investigation into Russian interference in the 2016 election.

Mueller is close to issuing his conclusions on two of the most controversial aspects of his investigation, according to Bloomberg News: Whether President Trump’s 2016 campaign colluded with Russia, and whether the president obstructed justice.

Mueller’s findings, however, may not be publicly released. It’s up the the discretion of Deputy Attorney General Rod Rosenstein, who is overseeing the probe, to decide what is turned over to Congress and what is released to the public.

The special counsel is not likely to conclude his entire investigation before the November midterm elections, which brings uncertainty about the investigation’s future as Trump has signaled he could replace Attorney General Jeff Sessions after the election.

There are also questions about Rosenstein’s future at the Justice Department after the New York Times reported he suggested secretly recording his conversations with Trump.

A Sessions or Rosenstein departure could bring a new boss for Mueller.

Rosenstein has pushed Mueller to wrap up the investigation as soon as possible, the Bloomberg report said.

Mueller has thus far secured more than two dozen indictments or guilty pleas since he took over the investigation almost a year and a half ago.
