Washington (CNN) President Donald Trump asserted Monday that he has the right to pardon himself but suggested that he won't use that power, adding that the special counsel investigation is "unconstitutional."

"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? In the meantime, the never ending Witch Hunt, led by 13 very Angry and Conflicted Democrats (& others) continues into the mid-terms!" the President tweeted.

The President then called Robert Mueller's investigation "UNCONSTITUTIONAL" but said he would "play the game" because he has "done nothing wrong." Mueller was appointed by Deputy Attorney General Rod Rosenstein, who was appointed by Trump.
