Jon Sale's legal work for Rudy Giuliani is ending, Sale confirmed to Law.com on Tuesday. That's about two weeks after Sale confirmed he was representing Giuliani, President Donald Trump's personal lawyer, in the congressional impeachment investigation into Trump and his foreign affairs.

Sale, a former Watergate prosecutor now practicing at Nelson Mullins Riley & Scarborough, dismissed reports that indicated he and Giuliani were parting ways as Giuliani himself was under a federal investigation. Sale said his representation of Giuliani did not end prematurely and said the scope of his engagement was limited to responding to a congressional subpoena.

"That's the scope of my engagement and I've completed it as a lawyer. It's really inaccurate to read anything more into it," he said. "There's no split between us."

Sale said his work for Giuliani was completed earlier in the day Tuesday. According to several press reports, Sale's letter to Congress said Giuliani wouldn't comply with the subpoena.

The end of Sale's representation comes as news organizations have reported that federal prosecutors in the Southern District of New York have been investigating Giuliani. The investigation into Giuliani has been tied to the case against two of his associates who were arrested on campaign finance-related charges, according to a New York Times report.

Sale, in the brief interview Tuesday, said any criminal investigation had "nothing to do" with the end of his representation of Giuliani. "I haven't been involved in that," Sale said. "I have not been contacted by anyone in the Southern District."

Sale said he also couldn't comment on his Nelson Mullins colleague, Trey Gowdy.

Gowdy's representation of Trump for the impeachment investigation was announced last week. However, that now appears in doubt, with the Times reporting Nelson Mullins had concerns that his work would involve lobbying activity.

A Nelson Mullins representative did not immediately return a message seeking comment. Giuliani also could not immediately be reached.
