In case you checked out during Maddow's monologue. This is what she's talking about except she dug into CIS and it's founder's even worse history.

Donald Trump is out with his first TV ad of the general election, and it’s predictably despicable: an image of “Hillary Clinton’s America” being flooded with refugees and “illegal immigrants convicted of committing crimes” while “the system stays rigged against Americans.” The ad has drawn comparisons to the infamous anti-immigrant ad that California Gov. Pete Wilson ran in 1994 as he was trying to push through a ballot measure imposing draconian penalties on undocumented immigrants.
