Donald Trump's lawyers have apologised following a legal gaffe where they sent a subpoena to the wrong person.

Last month, Trump's attorneys in his criminal hush money case in Manhattan sought to subpoena Jeremy Rosenberg, who was a supervising investigator in the Manhattan district attorney's office.

However, they accidentally sent the request to a Brooklyn man, also named Jeremy Rosenberg, who emphasised that he is a different person by e-mailing them back: "I don't have any files for you."

He also said he would keep the $15 sent to him to cover the postage charge for the files he did not possess.

Trump attorney Todd Blanche sent the subpoena to a man they believed to be former District Attorney Supervising Rackets Investigator Jeremy Rosenberg in March, seeking files related to Trump’s fixer-turned-enemy Michael Cohen.

Blanche had complained earlier this week that the man they believed was the ex-DA Rosenberg had displayed a "flippant and dismissive approach” to the request."

However, prosecutor Matthew Colangelo wrote in a filing: "The people spoke with Mr Rosenberg's counsel, who informed the People that Mr Rosenberg was not, in fact, served with the subpoena, that Mr Rosenberg had not corresponded with defence counsel, and that Mr Rosenberg does not have any connection to the Brooklyn address where the subpoena purportedly was served."

In his email, Rosenberg responded to the false claim saying: "PS - The phone number you provided was disconnected. PPS - I'm keeping the fifteen dollars."

​The Republican presidential candidate is accused of covering up a $130,000 hush money payment his former lawyer Michael Cohen made to porn star Stormy Daniels for her silence ahead of the 2016 election about a sexual encounter she says she had with Trump in 2006.

Trump has pleaded not guilty to 34 counts of falsifying business records and denies any such encounter with Daniels.

Earlier this week, Trump's lawyers told a New York appeals court judge multiple times that the former US president's April 15 trial should be delayed.

They argued the judge has not yet ruled on their motion for him to recuse himself, in his third last-ditch attempt so far this week to delay the case.

The case is one of four criminal indictments Trump faces as he prepares to challenge Democratic President Joe Biden in their November 5 US election rematch.

He has sought to delay proceedings in all cases until after the election, and the hush money case is the only one with a firm trial date.

The other cases stem from his efforts to overturn his 2020 election loss to Biden and his handling of sensitive government documents after leaving the presidency in 2021.

Trump has pleaded not guilty to all charges.
