A federal appeals court has blocked President Donald Trump’s executive order issuing an immigration ban barring people from seven predominantly Muslim countries from entering the United States. Trump also has made moves toward building a border wall with Mexico, which recent figures suggest may cost an estimated $21 billion.
To get into what these moves would actually accomplish, Julian Zelizer and I took a deep dive into immigration and border control with Doug Massey, one of the country’s leading experts in this field. Massey busted many myths, including the question of whether the effect of a border wall is to keep people out of the United States – or cage them inside.
Bonus: Doug Massey has made a cool appearance on Adam Ruins Everything to explain these points. Scroll to 3:20. Doug is hilarious.
