Yes this issue came up in the news earlier and seems to be lost in the euphoria of the current Mueller Russian influence investigation, arrest warrants and all. The President of the United States has the power to pardon anyone. The Power to Pardon could be is very powerful tool to allay fears of potentially guilty people close to the President. Cover-ups of Russian financial dealings breaking American tax law can be pardoned and an assumption could be made that anything beyond treason could be pardoned and perhaps treason itself. Of course the 5th amendment can be applied to anything self-incriminating. And an argument was made early on about the possibility of the President pardoning himself. Remember, Richard Nixon was pardoned.
