Richard Painter, who served as George W. Bush's White House ethics lawyer, said the key to special counsel Robert Mueller's probe will be deciding why President Donald Trump fired FBI Director James Comey.
Mr Mueller is furthermore said to be looking into the Oval Office meeting in which Mr Trump told Russian officials that firing "nut job" Federal Bureau of Investigation chief James Comey in May had relieved "great pressure" on himself.
Mr Mueller has previously indicated to the White House that he may interview six of the president's closest present and past advisers.
