contacts with russia. >> i was honestly concerned that he might lie about the nature of our meeting. >> reporter: comey was so worried about the president, he provided the details of one of the memos to the press. >> i asked a friend of mine to share the content of the memo with a reporter. i asked him to because i thought that might prompt the appointment of a special counsel. >> reporter: the inspector general bluntly says comey was wrong to secretly keep his memos and to leak writing, comey set a dangerous example for the over 35,000 current fbi employees. president trump tweeted that comey should be ashamed of himself and that the inspector general's report leaves him disgraced and excoriated. >> he gave it to a friend to leak classified information. he did an illegal act. >> reporter: but the inspector general, while sharply critical of comey, did not find that he gave any classified information to the press, and the justice department chose not to prosecute. former fbi director comey was defiant pointing out there was no evidence that he leaked classified information and that
