McCabe also put in the memo that he told Rosenstein that he just opened an investigation into President Trump over possible collusion and obstruction.
A newly released two-page memo written by then-Acting FBI Director Andrew McCabe outlined how former Deputy Attorney General Rod Rosenstein proposed wearing a wire in the White House "to collect additional evidence on the president’s true intentions," and thought the scheme was plausible because "he was not searched when he entered the White House."
The contemporaneous memo, which the Justice Department released after a transparency lawsuit by Judicial Watch, provided the strongest documentary evidence to date to undercut previous claims by DOJ officials that Rosenstein was joking when he apparently made the suggestion.
McCabe said in the partially redacted memo – written May 16, 2017, on the eve of Special Counsel Robert Mueller's appointment -- that Rosenstein offered to wear a recording device to gather evidence on the firing of former FBI Director James Comey and related matters. McCabe noted that he took Rosenstein's suggestion seriously enough that "I told him that I would discuss the opportunity with my investigative team and get back to him."
"As our conversation continued, the DAG proposed that he could potentially wear a recording device into the Oval Office to collect additional evidence on the president’s true intentions," McCabe wrote in the memo. "He said he thought this might be possible because he was not searched when he entered the White House."
