He can do it before then, but there is some stigma associated with that, as in, "she would have been indicted otherwise." Ford pardoned Nixon to take public attention off the issues.

Given Crooked a pardon would be a gross short-circuiting of the law, given her likely connection to pay-for-play for substantial government approval, maybe even approvals that were not in the country's best interest.
