Prosecutors called it a step that would be appropriate to ensure the lawyer-client privilege is protected, and filed the application under seal last Thursday, the day after the search was conducted. The letter was not sealed Tuesday.
The submission from prosecutors said they had consulted Giuliani’s lawyer and that he would file a response.
After federal agents executed search warrants in Giuliani’s apartment and office in Manhattan last week, Costello said the authority described an investigation into possible violations of foreign lobbying laws and that it sought communications between Giuliani and people that included a former columnist for The Hill , John Solomon.
“Hope the people whose information is privileged, like Donald Trump, will attend the trial and say look, you can not see my stuff,” Dershowitz, a retired Harvard Law School professor who served on the then president’s defense team in the first indictment lawsuit, and whose career has mostly been focused on individual civil liberties, CNN reported.
Costello told CNN Monday night that Giuliani’s legal team is ready to expand with additional attorneys as the former mayor of New York prepares for a legal battle, but that there had been no coordination between Giuliani and Trump’s legal team.
Another court document set out a briefing plan giving Giuliani until May 10 to respond to the prosecution’s submission.
