In response to Hillary Clinton's remark at her first debate with Trump to the effect that she was being made to blame for everything, by the Trump campaign, Trump interjected "Why not?"
One of the things that Trump tries to hang, like an albatross, around her neck, is NAFTA, the North American Free Trade Agreement.
This was a treaty that was wholly negotiated during the George H.W. Bush Administration. It was a treaty that George H.W. Bush signed, during the last days of his term. The treaty was ratified, by the Senate, during the term of the next President, Bill Clinton.
At the time of both the signing and ratification of the NAFTA treaty, Hillary was not only not in power but not an official of the Government, but as Trump aptly put it, "Why not blame (her for it)?"
