Presidents can pardon or grand amnesty for _ crimes

The president's pardon power is limited to federal offenses; the Constitution only grants the president the power to pardon "[o]ffenses against the United States." An offense that violates state law, but not federal law, is an offense against that state rather than an offense against the United States.

Explanation:

the ss was the main organization responsible for the genocidal murder of around six million people of european ethnic minorities, essentially jews, in the holocaust. the members of all its branches committed war crimes and crimes against humanity during the second world war (1939-1945). likewise, the ss were involved in commercial enterprises and exploited the inmates of the concentration camps as slave laborers.

the tortures and assassinations committed by the ss were the result of an ideology developed long before the armed conflict, this ideology was based on the racial supremacy of the germans over the rest.
