Washington (CNN) Donald Trump's personal attorney Michael Cohen has signaled to friends that he is "willing to give" investigators information on the President if that's what they are looking for, and is planning on hiring a new lawyer to handle a possible indictment from federal prosecutors.

"He knows a lot of things about the President and he's not averse to talking in the right situation," one of Cohen's New York friends who is in touch with him told CNN. "If they want information on Trump, he's willing to give it."

Cohen is planning to hire Guy Petrillo, a former chief of the criminal division of the US attorney's office in Manhattan and an experienced trial lawyer, a source familiar confirmed. The source said all the paperwork and retainer may not have been finalized just yet.

Last week, CNN reported Cohen has indicated a willingness to cooperate to alleviate pressure on himself and his family.
