Usually, it's not a good thing when lawyers need lawyers.
And if an attorney goes to the opposition, it's worse. That's Michael Cohen, President Trump's former lawyer, right now.
Cohen has turned to Lanny Davis, President Clinton's former attorney, for help. Who is he and what could possibly go wrong?
Former Clinton Lawyer
Davis, a Democrat, served as special counsel to former President Bill Clinton in the 1990s. After leaving the White House, Davis defended Clinton as a commentator during the ex-president's impeachment proceedings.
He also supported Hillary Clinton during the 2016 presidential campaign. He recently wrote a book, The Unmaking of the President 2016, criticizing FBI Director James Comey for his investigation into her use of private email as secretary of state.
In other words, Davis is not a Trump fan. Legal observers see that as a bad sign for the president.
"Michael Cohen deserves to tell his side of the story -- subject, of course, to the advice of counsel," Davis said.
Cohen, Trump's longtime fixer, has played it close to the vest after the FBI raided his office and residences in early April. He is under investigation, in part, for his role in paying Stormy Daniels $130,000 in hush money before the 2016 election.
But he may have tipped his hand in a recent interview with ABC News, apparently distancing himself from the President.
"My wife, my daughter and my son have my first loyalty and always will," Cohen told ABC's George Stephanopoulos.
