"Mr. Cohen underwent serious shoulder surgery and this extra time allows Mr. Cohen to continue his physical therapy", a statement said.
The House Oversight Committee, now led by Democrat Elijah Cummings, announced on Wednesday that it will hold a public hearing next Wednesday at which Cohen will be the only witness.
Cohen is due to turn himself in on March 6 to begin serving a three-year prison sentence. The panel subpoenaed him earlier this year.
"Despite @RealDonaldTrump attacks against his family, Mr. Cohen will not be deterred, will speak about his decade long experiences working for Mr. Trump, his own mistakes and decision to put family and country first", Cohen lawyer Lanny Davis tweeted after the rescheduled hearing was announced. "Congress has an obligation under the Constitution to conduct independent and robust oversight of the Executive Branch, and this hearing is one step in that process".
Cohen, President Donald Trump's former personal attorney and fixer, is also preparing to testify before three Congressional committees this month. They noted prosecutors did not object to the one-time extension.
The scheduled public hearing sets the stage for what is expected to be one of the most high profile congressional testimonies in history, although Cohen will not talk about matters related Special Counsel Robert Mueller's Russian Federation probe or an ongoing investigation by federal prosecutors in New York, Cohen's lawyer, Lanny Davis said last week.
Earlier Wednesday, Cohen, who pleaded guilty to campaign finance violations for making hush-money payments to two women who claimed they had affairs with Trump, got a 60-day reprieve before he has to enter a federal prison.
He also pleaded guilty to campaign finance violations for his involvement in payments to a former Playboy model and porn actress who had alleged affairs with Trump.
In a letter requesting the delay dated Wednesday, Cohen attorney Michael D. Monico cited a "more fulsome letter" sent to Pauley eight days ago by Cohen that was sealed.
In May 2018, Fry, who works in the IRS' San Francisco office, accessed and downloaded five SARs connected to Cohen, according to the complaint, and then, seeing that other such documents were unavailable in the database, turned over some of the SARs to Avenatti and told The New Yorker reporter that he was alarmed to see other SARs were inaccessible, the complaint says.
