Rudy Giuliani will defy House Democrats’ impeachment subpoena, a letter his attorney sent to Congress on Tuesday said.

Jon Sale, Giuliani’s attorney sent a letter to Congress informing them that Giuliani will not be providing documents that were requested by subpoena.

The Office of Management and Budget also does not plan to turn over the documents that impeachment committees subpoenaed, a spokeswoman said, pointing to a letter earlier this month from White House counsel Pat Cipollone saying it speaks for OMB as well.

The White House letter slammed the impeachment investigation as “constitutionally illegitimate” and made clear the administration does not plan to cooperate.

Giuliani is also now parting ways with his personal attorney Jon Sale who has represented him in impeachment matters, Giuliani told CNN.

Sale will stop representing the former New York City mayor shortly, Giuliani told CNN.

Sale had been working for Giuliani after the House of Representatives subpoenaed Giuliani for documents related to the ongoing impeachment inquiry.

“Jon was helping me with assessing (the) congressional request. He will submit his letter and he will be finished with what I asked him to do,” Giuliani said.

People close to Giuliani are advising him to hire a criminal lawyer as questions linger about his connections to two of his associates, Lev Parnas and Igor Furman, who were indicted last week for campaign-finance violations. Giuliani, who is President Donald Trump’s personal attorney, has been resisting that advice, according to those people.

Giuliani did not directly answer whether he was looking to hire a new attorney for himself.

“If they take me to court I would then have to get another lawyer,” he told CNN.

Taking on a criminal attorney would likely cost Giuliani something close to $1 million, according to people in New York legal circles. That could be difficult for Giuliani, who admitted earlier this year that he had to take a $100,000 loan from another of Trump’s lawyers Marc Mukasey as a result of his ongoing divorce proceedings, according to a report from Bloomberg.
