Presidental pardon for those not yet charged?

Factual Questions
1

I have seen some news media propaganda about obama pardoning clinton. That leads me to a question. Can a president pardon someone who has not yet been charged with a crime?

2

Sure - see Ford’s pardon of Nixon - Proclamation 4311 - Wikisource, the free online library

IANAL.

President Ford pardoned Nixon as well as Carter’s pardon of Vietnam War draft evaders who had not yet been charged. So precedent seems to say that a preemptive pardon is within the president’s purview.
