In a statement Wednesday night, Grassley questioned whether leaking the memos to a Columbia professor would violate department policies.
Grassley also wrote a letter to Deputy Attorney General Rod RosensteinRod RosensteinWashington still needs more transparency House Judiciary to probe DOJ's seizure of data from lawmakers, journalists The Hill's Morning Report - Biden-Putin meeting to dominate the week MORE to learn more about the chain of custody for the memos, and whether Rosenstein has initiated an investigation into Comey's handling of the memos.
Multiple memos Comey wrote as personal recollections of his interactions with President Trump about the Russia investigation contained classified information.
Comey told the Senate Intelligence Committee last June that he shared at least one of the memos, which he considered personal documents, with a law professor at Columbia University. He then asked that professor to leak the information from one memo to the media in the hopes of increasing pressure to get a special prosecutor named in the Russia investigation.
Comey testified that he believed his personal memos were unclassified.
President Trump fired Comey in May.
