In remarks this weekend concerning the Southern border, Former Pres. Donald Trump used a collection of controversial rhetoric to talk about immigration in this country, saying they are quote "poisoning the blood of our country," which was quickly rebuked by the Joe Biden campaign which likened the words to those of Adolf Hitler. 

This comes as the Biden administration has been facing tough choices on border policy as crossings continue to strain federal resources and congress hasn't been able to come together on new policies.

To answer those questions and more, KCBS Radio's Margie Shafer and Eric Thomas spoke with Alexandra Filindra, Political Science Professor at the University of Illinois Chicago, she researches immigration policy, public opinion and political psychology.
