Andy talks with Michael about his June Foreign Affairs article, "The Terrorism Warning Lights Are Blinking Red Again: Echoes of the Run-Up to 9/11," co-written with Graham Allison. Michael discusses the pre-9/11 threat and national security parallels with today's environment. He also shares his assessment of a newly unsealed 1999 video from Saudi intelligence officer Omar al-Bayoumi, which Michael says appears to be 'casing' footage of the US Capitol. Additionally, Michael talks with Andy about the security vulnerabilities at the US-Mexico border.
