The Washington Roundtable: Prospects for the passage of a long-negotiated aid package that includes funding for Ukraine and Israel, and policy changes for the U.S. southern border, rapidly shrank this week, after the deal met resistance from House Republicans and former President Donald Trump. Meanwhile, President Biden’s approval rating on immigration has sunk to eighteen per cent. Why are Republicans simultaneously concerned about the crisis at the border while also stymying bi-partisan legislation to address it? The New Yorker staff writer Jonathan Blitzer, who is the author of “Everyone Who Is Gone Is Here: The United States, Central America, and the Making of a Crisis,” joins the hosts Susan B. Glasser, Jane Mayer, and Evan Osnos to weigh in on the implications that our knotted immigration politics have for the 2024 election.
