Congress returns, Iowa Primary, and the Iran stalemate

Congress returns from recess with several unresolved items on the agenda. Playbook’s Jack Blanchard and Dasha Burns walk through the stalled immigration spending bill, an upcoming war powers vote, and the mood among some Republican senators following the Texas primary. Then, a Democratic Senate primary in Iowa tomorrow and what it signals about Chuck Schumer’s role as a Democratic leader. Plus: the latest on Iran negotiations, which remain at a standstill.
