The hotly anticipated report from special counsel Robert Mueller is due for release Thursday morning, but not before Attorney General William Barr holds a press conference that Democrats have denounced as yet another ploy to protect President Trump.

Nearly one month ago Mueller’s expansive investigation came to a close, ending a yearslong inquiry into Russian interference in the 2016 election, possible collusion between the Trump campaign and the Kremlin, and an examination of whether the president obstructed justice. Within two days Barr submitted a four-page letter to Congress he said was meant to “summarize the principal conclusions,” and although Trump and his allies saw exoneration in its contents, Democrats raised the alarm about what they feared was a cover-up due to the summary only sparsely quoting Mueller’s actual report.
