In December 2018, Brennan tweeted that Trump should prepare for the "forthcoming exposure of your malfeasance & corruption." One day after the release of the Barr letter in March 2019, Brennan said on MSNBC: "Well, I don't know if I received bad information, but I think I suspected there was more than there actually was. I am relieved that it's been determined there was not a criminal conspiracy with the Russian government over our election...I still point to things that were done publicly, or efforts to try to have conversations with the Russians that were inappropriate, but I’m not all that surprised that the high bar of criminal conspiracy was not met.” The Barr letter was criticized by many as deceptive after the release of the Mueller report weeks later, with Mueller writing to Barr that the letter “did not fully capture the context, nature, and substance” of Mueller’s work.
