Special counsel Robert Mueller’s report, due for release on Thursday, is expected to detail President Donald Trump’s efforts to interfere with FBI investigations into contacts between his 2016 campaign and Russia. In particular, the report may discuss Trump’s attempt to convince former Attorney General Jeff Sessions to undo his decision to recuse himself from overseeing the Russia matter. Sessions rebuffed Trump’s demand that he take control of the probe—a choice that ultimately paved the way for Mueller’s appointment and helped create a major rift between the president and his first attorney general.
