Famous law professor at GWU Law School:

The admission of leaking the memos is problematic given the overall controversy involving leakers undermining the Administration. Indeed, it creates a curious scene of a former director leaking material against the President after the President repeatedly asked him to crack down on leakers.
Besides being subject to Nondisclosure Agreements, Comey falls under federal laws governing the disclosure of classified and nonclassified information. Assuming that the memos were not classified (though it seems odd that it would not be classified even on the confidential level), there is
18 U.S.C. § 641 which makes it a crime to steal, sell, or convey “any record, voucher, money, or thing of value of the United States or of any department or agency thereof.”

By the way, waking up in the middle of the night (as described by Comey) is not generally the best time to decide to leak damaging memos against a sitting president. There are times when coffee and a full night’s sleep (and even conferral with counsel) is recommended. Leaking damaging memos is one of those times. Moreover, if Comey was sure of his right to release the memo, why use a law professor to avoid fingerprints?
I find Comey’s admission to be deeply troubling from a professional and ethical standpoint. Would Director Comey have approved such a rule for FBI agents? Thus, an agent can prepare a memo during office hours on an FBI computer about a meeting related to his service . . . but leak that memo to the media. The Justice Department has long defined what constitutes government documents broadly. It is not clear if Comey had the documents reviewed for classification at the confidential level or confirmed that they would be treated as entirely private property. What is clear is that he did not clear the release of the memos with anyone in the government.
Comey’s statement of a good motivation does not negate the concerns over his chosen means of a leak. Moreover, the timing of the leak most clearly benefited Comey not the cause of a Special Counsel. It was clear at that time that a Special Counsel was likely. More importantly, Comey clearly understood that these memos would be sought. That leads inevitably to the question of both motivation as well as means.
