Donald Trump, on his way to California to visit his baby wall prototypes, cited an anti-immigrant hate group that has promoted pieces authored by anti-Semites and Holocaust deniers:

As the Southern Poverty Law Center reports, CIS “has gone on to become the go-to think tank for the anti-immigrant movement with its reports and staffers often cited by media and anti-immigrant politicians.” But make no mistake, this is a hate group:

The Center for Immigration Studies, like the rest of the organized anti-immigrant movement we see in America today, was founded by John Tanton, a Michigan ophthalmologist turned population control alarmist whose racist beliefs stirred him to create a network of organizations with a simple agenda: heavily restricting the immigration levels to the United States in order to maintain a white majority. As Tanton himself wrote in 1993, "I've come to the point of view that for European-American society and culture to persist requires a European-American majority, and a clear one at that."

According to Think Progress, “Tanton is a strict nativist who once wrote a paper titled ‘The Case for Passive Eugenics.’” Charming. And that’s who the president of the United States cited today.
