Sitting presidents cannot be indicted. Even if they could, it would be unlikely in this multi-tiered justice system.
The President is the sole member of the Executive Branch of the United States. This branch (president) is responsible for law enforcement per The Constitution. This makes The President the chief law enforcement officer in the country. Thus, it is impossible for presidents to obstruct justice since presidents ARE justice. --They cannot possibly obstruct themselves. --Also Robert Mueller has agreed that sitting presidents cannot be indicted for anything. They may be impeached which is the remedy that The Constitution provides. ---Please read and understand The Constitution so you don't look so foolish in the future. Remember---The Constitution is a negative liberty document.
A sitting president cannot be indicted, he can only be impeached. ----Impeachment of a president is the only Constitutional remedy to remove a president. Even if it were so, an indictment would be stayed until after a president left office and would never pass muster anyway since presidents have the constitutional authority to pardon themselves with or without charges. Folks need to bone up a bit on the Constitution.
