Attorneys Stephen Ryan and Todd Harrison from NY firm McDermott, Will & Emery LLP had previously been representing Cohen.
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.
Neither Cohen, Ryan nor Harrison immediately responded to messages Wednesday.
Both ABC and The Wall Street Journal reported Weednesday that the firm will cease representing Cohen after a review of the documents seized has been completed. Stormy Daniels, the adult film star who claims she had sex with Trump in 2006 and was then paid $130,000 to keep quiet about it, has also asked to join the case. Trump tweeted after the raid.
It's not clear what ABC's sources believe is the link between the lawyers dumping Cohen and his potential cooperation with prosecutors.

Gadot, along with Jenkins and Zack Snyder are listed as producers of the DC film, which has begun principal photography. Filming is taking place in Washington, D.C., Alexandria, Virginia, and in the UK, Spain, and the Canary Islands.
According to the Journal, Cohen is looking for a federal criminal lawyer in NY, preferably one with close connections to the Manhattan U.S. attorney's office. When reached for comment by Vanity Fair, the lawyer replied, "Your alleged source is wrong!"
Mr. Cohen hasn't yet decided whether he will cooperate with prosecutors in the case, according to one of those people.
"If anyone can blow up Trump, it's him", an unnamed White House official told Vanity Fair.
Cohen - whose office, home, and hotel in NY were raided by FBI agents in April - is under investigation for wire fraud, bank fraud, and campaign finance violations. But these are his only two real options, as his case plays out in the Southern District of NY.
The AP reports federal prosecutors in NY have publicly said they are investigating alleged fraud in Cohen's business dealings, but haven't disclosed details.
