When Claire was talking to the woman during the campaign, we heard that the woman said, "like when he pardoned Walker and the other guy, the rich one"
I understand why he pardoned Tusk, but why would Walker be subjected to charges if he was the President of the United States, which in my knowledge, cannot be persecuted.
Is it because he 'was' the POTUS when he resigned, so he could be charged again with cases he did during his presidency; or because the alleged corruption was done before he became the POTUS, which is during his campaigning.
