President Donald Trump has vowed to tackle immigration on “day one,” and that includes promising to close the southern border and begin mass deportations almost immediately. So who better to discuss the plausibility of those imminent plans than the man who led immigration policy at the Department of Homeland Security for the past four years, former Secretary Alejandro Mayorkas? Kara sits down for an exit interview with Mayorkas to talk about the backlash he faced, from both sides of the aisle, during a term plagued by “Biden’s Border Crisis”; whether he feels responsible for Trump’s election victory; his assessment of the threats posed by foreign and domestic extremists; his thoughts on calls to break up the mammoth DHS; and what he makes of his tapped successor, South Dakota Governor Kristi Noem.
