When the President was an un-indicted co-conspirator.
Richard Nixon was President, so he couldn't be prosecuted in normal courts, as were his associates. But he was named as an un-indicted co-conspirator in indictments of others.
Hopefully this will happen soon to DT.

WASHINGTON, June 6President Nixon was named last February by a Watergate grand jury as an unindicted co‐conspirator in the alleged attempt to cover up the Watergate burglary, his lawyer, James D. St, Clair, confirmed today.
The disclosure, which had been closely guarded in secret court hearings on the case, completes the circle of conspiracy alleged in the indictment handed up March 1 by the grand jury and explains what was contained in the mysterious briefcase handed to Federal Judge John J. Sirica at that time.
It is expected to have a significant impact on the upcoming trials, tying in the President's remarks and meetings with aides in the Watergate matter as possible evidence in the case, rather than excluding them as merely comments of an outsider whose aides were conspiring.
Effect of the Action
If they tie him into these crucial meetings, this means there's an umbilical between him and us, said one defense attorney for the six men charged in the cover‐up conspiracy. That's what troubles me.
