Tracking 'Breakthrough' COVID Infections; The City's Economic Recovery; Biden's Call for Gun Control; When Your Student Loans Don't Qualify for Relief

Coming up on today's show: 

• Katherine Wu, staff writer at The Atlantic who covers science, talks about why "breakthrough" COVID infections -- which happen after people are fully vaccinated -- are inevitable, and why they are important to track.  
• Greg David, contributor covering fiscal and economic issues for THE CITY and director of the business and economics reporting program and Ravitch Fiscal Reporting Program at the Newmark Graduate School of Journalism, talks about his 5-part series examining the impact of the pandemic on the New York City economy.
• President Joe Biden called for tightening gun control laws in the wake of two mass shootings in less than a week. Jennifer Mascia, a news writer at The Trace, a non-profit newsroom focusing on gun violence, talks about Biden's history on the issue and whether Democrats can pass any meaningful reform with the filibuster still in place.
• Congress included federal student loan relief with the COVID legislation -- yet millions find their loans don't qualify. Molly Webster, Radiolab senior correspondent, talks about her recent New York Times op-ed explaining how she borrowed $78,000, has paid $60,000, and still owes $100,000 -- with no relief in sight.
