No, she does not have to be charged.

Nixon wasn't charged. Jimmy Carter's draft dodgers mostly were not charged. Garland wasn't charged and neither were many former Confederates who received pardons/amnesties.

Thus, Ex Parte Garland notes that pardons "...may be exercised at any time after its [the crime's] commission, either before legal proceedings are taken..."

Not really. Ford pardoned Nixon, and he hadn't been charged. Plus Judge Napalitano was on Fox Business, discussing this, and said that it was not necessary.
