(CNN) Rudy Giuliani has been approaching defense attorneys for possible representation, according to three sources familiar with the matter.

The move by Giuliani, who is President Donald Trump's personal attorney, is notable because last week he said he would not be seeking a new lawyer unless he felt one was needed. His previous lawyer, John Sale, was helping him deal with congressional inquiries.
