In an interview that aired Sunday, President Trump’s attorney, Rudy Giuliani dropped a bombshell. Telling ABC News that the president has the power to pardon himself should he ever be legally implicated.

According to ABC News:

President Donald Trump’s personal attorney said the commander-in-chief “probably does” have the power to pardon himself.

In an interview Sunday with ABC News Chief Anchor George Stephanopoulos on “This Week,” Rudy Giuliani discussed special counsel Robert Mueller’s investigation of whether the president may have tried to obstruct justice in the probe of Russian efforts to interfere in the 2016 U.S. presidential election.

When Stephanopoulos asked if the president has the power to pardon himself, Giuliani said he “probably does.”

“He has no intention of pardoning himself,” said Giuliani, a former New York City mayor who is Trump’s lead attorney in negotiating an end to Mueller’s ongoing investigation. But it is a “really interesting constitutional argument: ‘Can the president pardon himself?'”

Should the investigation lead to an indictment of a sitting president, something that is against DOJ protocol, this would be an interesting battle to watch unfold.
