Rudy Giuliani is parting ways with the personal attorney who has represented him in matters related to the impeachment inquiry. Giuliani told CNN Tuesday that his current attorney, Jon Sale, will stop representing the former New York City mayor shortly.

Sale had been working for Giuliani after the House of Representatives subpoenaed Giuliani for documents related to the ongoing impeachment inquiry. The deadline for his response to the congressional subpoena is Tuesday.

"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.

Sale did not respond to multiple requests for comment.

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.
