President Trump's attorney Rudy Giuliani said on ABC News' "This Week" that Trump "probably does" have the power to pardon himself if special counsel Robert Mueller's investigation found him guilty of obstructing justice in the Russia probe.
He's not, but he probably does. He has no intention of pardoning himself, but that doesn't say he can't. That's really interesting constitutional argument: 'Can the president pardon himself? ... It would be an open question.
— said Giuliani, when host George Stephanopoulos asked if Trump has such authority.
