WASHINGTON — President Donald Trump declared Monday that he has the “absolute right” to pardon himself, but added he had done nothing wrong, asserting his presidential power as the White House is sharpening its political and legal defenses against the special counsel Russia probe. Trump’s comments on Twitter came a day after attorney Rudy Giuliani played down the possibility that the president could pardon himself, suggesting he might have that authority but would be unwise to use it. As has been stated by numerous legal scholars, I have the absolute right to PARDON myself, but why would I do that when I have done nothing wrong?
