As talks of reviving the 2015 nuclear deal —alternatively known as the Joint Comprehensive Plan of Action — come to a halt, it’s unclear why Iran and key players involved in the deal, like the United States, have stalled negotiations. Between Russia causing global tension by invading Ukraine and America refusing to lift or alter Russian sanctions for the sake of the nuclear deal, the next step in negotiations remains unclear. Texas Republican Congressman Michael McCaul joins to discuss how the Russia Ukraine conflict has impacted nuclear negotiations, why 49 out of 50 Republicans don’t support the current deal, and what we should expect if Iran is given easier access to nuclear power. This week, NASA astronaut Mark Vande Hei broke the record for the most consecutive days spent in space by an American. While this would normally be cause for a celebration, there's growing concern over his return from the International Space Station (ISS) amid current tensions with Russia over its invasion of Ukraine. Despite sanctions placed on Russia and the ambiguous future of the ISS, NASA has said that plans for Vande Hei's homecoming remain unchanged. Homer Hickam, a former NASA engineer and author of Rocket Boys and Don't Blow Yourself Up, joins the Rundown to discuss the history of our relationship with Russia and space, the current state of the ISS, and his thoughts on Vande Hei's safe return.
