Special counsel Robert Mueller’s team argued against the release of former FBI Director James Comey’s memos that contained notes he took during his infamous one-on-one meetings with President Trump.

A transcript of a January 2018 court hearing, released Tuesday on a court order, shows Mueller’s prosecutors were worried Trump and other witnesses might alter their stories depending on what they saw in the memos. In fact, Mueller’s team was seeking an interview with the president himself at the time.
