A lot of nonsense has been written here about importance of Grand Jury. It is a normal proceeding if such avenue is chosen. No clear legal answer exists to the question of whether a sitting President can be indicted and prosecuted.  The Attorney General’s Office of Legal Counsel has considered this issue in depth twice in the past half-century.

Richard Nixon was the only president in U.S. history to resign from office — doing so on Aug. 9, 1974, amid the Watergate scandal — but he was not, as is often stated, impeached by the House of Representatives.

The two presidents who were impeached by the House were Bill Clinton, in 1998, and Andrew Johnson in 1868 — though both were acquitted by the Senate.
