The Constitution does not answer every question. It includes detailed instructions, for instance, about how Congress may remove a president who has committed serious offenses. But it does not say whether the president may be criminally prosecuted in the meantime.
"A Constitutional Puzzle: Can the President Be Indicted?" is from the May 29, 2017 U.S. section of The New York Times. It was written by Adam Liptak and narrated by Barbara Benjamin-Creel.
