Whether or not that's the case (and whether or not Trump would consider a pardon) aside, it is notable that President Trump has reportedly been holding his tongue on Cohen matters because he doesn't want to give him more reason to flip and dig up dirt.
After FBI agents raided Cohen's office in April, Ryan and his NY partner, Todd Harrison, went to court to try to keep investigators from seeing some of the confiscated files on the grounds that they were protected by attorney client privilege.
Roughly 3.7 million files were seized in the Cohen raid and are being reviewed to determine which ones may be subject to attorney-client privilege.
It wasn't immediately clear what prompted the change or who would take over.
Cohen will hire a new lawyer for the next phase of the probe, the person said.
Earlier this week, Vanity Fair and the New York Daily News reported that Cohen has been telling friends he expects to be arrested any day now. When reached for comment by Vanity Fair, the lawyer replied, "Your alleged source is wrong!"
Trump at the time called the feds' raid "an attack on our country in a true sense" and has railed non-stop against special counsel Robert Mueller's investigation into Russian election meddling and possible collusion with the Trump campaign. But these are his only two real options, as his case plays out in the Southern District of NY. The issue is primarily over payment of the legal bills of one of his lawyers, Stephen Ryan, according to a person familiar with the discussions.
