Sen. Bernie Sanders, UN Ambassador Mike Waltz, Sen. John Kennedy

This week on Face the Nation, as the U.S. war with Iran approaches the 5 month mark, both sides are searching for a diplomatic off-ramp.
After nearly two weeks of striking targets across Iran following the collapse of the short-lived ceasefire earlier this month, the Trump administration paused its bombardment for two straight days for the first time, as diplomatic talks over the Strait of Hormuz show signs of progress.
With our new CBS poll showing continuing unease about the war's direction, we ask U.N. Ambassador Mike Waltz whether a peace deal is any closer.
Then, with midterm elections around the corner, Congress faces a daunting to-do list of must-pass legislation to fund the government and the war. We hear from Senators John Kennedy and Bernie Sanders on both foreign policy and politics.
