The Hill reported 4 of 7 memos were determined to have confidential information. Only 1 was given to the lawyer friend that passed on the information to NY Times. Only Fox News is claiming that of the for the 4 memos that have confidential information it was one of them given by Comey to the friend. Fox is citing the Hill yet "leaking confidential information" is not a claim they are making. Here is the article from The Hill. If it's determined that Comey mishandled classified information, he deserves to be prosecuted.
