The special counsel’s report on Russian interference in the 2016 presidential election has been released to the public at long last. All 400-plus pages of it.

But as lawmakers, journalists and lawyers for President Trump devour every detail in the highly anticipated report from Robert S. Mueller III, what was not made public may be just as important in shaping how the report is received.

After a closely guarded investigation captivated the American public for nearly two years, redactions to the final report have quickly become a sticking point. Democrats have expressed distrust over any attempt to filter their view of the treatise, with lawmakers demanding to see a full, unredacted copy. Tensions over transparency could lead to a subpoena or even send the issue to court.
