Over the course of the probe, which began previous year, Mueller and his team have looked for evidence of Russian interference in the 2016 presidential election, as well as possible collusion or obstruction of justice on Trump's part.
A report from Bloomberg indicates that "soon" might finally be here.
Specifically, Mueller is close to rendering judgment on two of the most explosive aspects of his inquiry: whether there were clear incidents of collusion between Russian Federation and Donald Trump's 2016 campaign, and whether the president took any actions that constitute obstruction of justice, according to one of the officials, who asked not to be identified speaking about the investigation.
"I committed I would ensure the investigation was appropriate and independent and reached the right result, whatever it may be", Rosenstein said.
The probe's supervisor then has discretion over what is given to Congress and what is revealed to the public.
Despite the costly nature of the investigation, Rosenstein believes the public will have faith in its findings. There's really only one party that would do that.
Mueller has secured more than two dozen indictments and guilty pleas so far in the investigation, which the president frequently complains is a "witch hunt".
