WASHINGTON Candidate Donald Trump bragged that he could shoot someone on New Yorks Fifth Avenue and not lose any support, and now President Donald Trump s lawyer says Trump could shoot the FBI director in the Oval Office and still not be prosecuted for it.

In no case can he be subpoenaed or indicted, Rudy Giuliani told HuffPost Sunday, claiming a presidents constitutional powers are that broad. I dont know how you can indict while hes in office. No matter what it is.

Giuliani said impeachment was the initial remedy for a presidents illegal behavior even in the extreme hypothetical case of Trump having shot former FBI Director James Comey to end the Russia investigation rather than just firing him.

If he shot James Comey, hed be impeached the next day, Giuliani said. Impeach him, and then you can do whatever you want to do to him.

Norm Eisen, the White House ethics lawyer under President Barack Obama and now a senior fellow at the Brookings Institution, said the silliness of Giulianis claim illustrates how mistaken Trumps lawyers are about presidential power.

A president could not be prosecuted for murder? Really? he said. It is one of many absurd positions that follow from their argument. It is self-evidently wrong.

Eisen and other legal scholars have concluded that the constitution offers no blanket protection for a president from criminal prosecution. The foundation of America is that no person is above the law, he said. A president can under extreme circumstances be indicted, but were facing extreme circumstances.

Giulianis comments came a day after The New York Times revealed that Trumps lawyers in January made their case to special counsel Robert Mueller that Trump could not possibly have obstructed justice because he has the ability to shut down any investigation at any time.

He could, if he wished, terminate the inquiry, or even exercise his power to pardon if he so desired, Jay Sekulow and John Dowd wrote in a 20-page letter. Dowd has since left Trumps legal team, replaced by Giuliani.

The letter also admits that Trump dictated a statement that was then released by his son, Donald Trump Jr. , regarding a meeting held at Trump Tower in June 2016 between top Trump campaign officials and Russians with links to that countrys spy agencies.

That meeting was scheduled after the Russians said they had damaging information about Democratic presidential nominee Hillary Clinton that would be of use to the Trump campaign. The Trump-dictated statement falsely claimed the meeting was primarily about the adoption of Russian children by American families the same topic that Trump claimed had been the substance of a conversation he had had with Russian leader Vladimir Putin the previous evening in Germany.
