(CNN) Florida attorney Jon Sale, who worked as an assistant prosecutor on the legal team investigating the Watergate scandal, is representing Rudy Giuliani in the matter of the congressional impeachment inquiry, Giuliani and Sale both confirmed to CNN on Tuesday.

Giuliani was subpoenaed on Monday by the three committees in the House of Representatives investigating President Donald Trump's interactions with the Ukrainian government . The subpoena requests documents and correspondence from Giuliani related to Ukraine.

Giuliani has so far declined to say whether he will comply with the subpoena. Reached by phone Tuesday, Sale told CNN he had just started looking into the requests.

"What I've already learned is this is very complex," Sale said when asked if Giuliani planned to comply. "I really have to study it. I can't shoot from the hip."

"Every time I turn around, Rudy's on another TV show," Sale continued. "He and I could have a conversation, and then I turn on the television and he could be doing something else."
