On July 30, former President Barack Obama, speaking at the funeral of Congressman John Lewis, threw his weight behind ending the Senate filibuster if necessary to pursue a voting rights agenda. His comments brought to the forefront a debate that has been simmering for years within the Democratic party. Margaret Taylor spoke with Adam Jentleson, who served as deputy chief of staff to Senate Democratic Leader Harry Reid during the Obama administration, and Brookings senior fellow Molly Reynolds, about the history of the filibuster, how it actually works and what the consequences could be if a Democratic-controlled Senate actually got rid of it.

This week on Lawfare's Arbiters of Truth series on disinformation, Alina Polyakova and Quinta Jurecic spoke with Shane Huntley, the director of Google’s Threat Analysis Group—a team that leads Google’s efforts to track threats from nation states and hacker groups. If you’ve ever received a notification from Google that a state-sponsored actor is trying to access your email account, you’ve heard from the Threat Analysis Group. The group examines everything from attempts to steal cryptocurrency to what Google calls “coordinated influence campaigns.”

Recently, the Threat Analysis Group has begun putting out blog posts with updates on their work against coordinated influence campaigns. Alina and Quinta asked Shane about his “bulletin” for the first quarter of 2020.

President Trump recently issued executive orders aimed at banning TikTok and WeChat from operating in the United States. To discuss the sanction, Bobby Chesney sat down with Dr. Sheena Chestnut Greitens, an associate professor at the LBJ School of Public Affairs at the University of Texas at Austin and a faculty affiliate with the Strauss Center for International Security and Law and the Clements Center for National Security at UT; and Dr. Ronald Deibert, a professor of political science and the founder and director of The Citizen Lab at the University of Toronto's Munk School of Global Affairs and Public Policy. In addition to the executive orders concerning TikTok and WeChat, they also discussed the larger U.S.-China relationship and the role of technology competition in that space.

Last week, the DC Circuit Court of Appeals in Washington handed down a major en banc decision on the question of whether the president's former White House Counsel, Don McGahn, even needs to show up in response to a congressional subpoena, or whether he has absolute immunity from testifying before Congress. A strong seven judge majority of the DC Circuit overturned a panel opinion that had held that a congressional committee had no standing to sue to enforce its subpoena. The full DC Circuit ruled that yes, it does have standing. In a separate case, a lower court ruled on an internecine dispute within the House of Representatives over proxy voting instituted by speaker Nancy Pelosi in response to the COVID-19 crisis. The court ruled that Republicans could not challenge the proxy voting rule because of the Speech and Debate Clause. Benjamin Wittes spoke with Lawfare senior editors Margaret Taylor and Scott Anderson about what this all means for congressional oversight, whether these opinions will stand up on further review and what will happen next.

During the Vietnam War, Richard Nixon employed an unusual scare tactic in his efforts to reach a withdrawal—he led Vietnam to believe he was crazy enough to start a nuclear war, an approach he described as the madman theory. From his first days in office, President Trump has employed his own madman theory, from menacing North Korea with fire and fury to threatening withdrawal from NATO, leaving not just adversaries, but also U.S. allies and even his own advisors unsure of what he will do next. David Priess spoke with CNN's chief national security correspondent and anchor of CNN Newsroom, Jim Sciutto, who has analyzed Trump's foreign policy through this lens and written "The Madman Theory: Trump Takes On the World."

Acting Secretary of Homeland Security Chad Wolf testified before the Senate Homeland Security and Governmental Affairs Committee on Thursday. He was asked about the recent DHS personnel deployments in the wake of mass protests, particularly in Portland, Oregon. The hearing included some grandstanding and repetition, but we cut out all of the theatrics to leave you with just the questions and answers that you need to hear.

This week on Lawfare's Arbiters of Truth series on disinformation, Evelyn Douek and Quinta Jurecic spoke with Ben Collins and Brandy Zadrozny, reporters at NBC News. Writing at NBCNews.com, they report on disinformation and misinformation in health and politics. Their work covers a lot of ground, but for this episode, they discussed one increasingly prominent issue on that beat: QAnon, a conspiracy theory built around anonymous posts on an internet forum claiming that Donald Trump is waging war against a deep state and a vast network of child sex traffickers. The conspiracy theory has inspired acts of violence and is becoming increasingly mainstream, with several candidates for U.S. Congress being QAnon believers. They talked about how QAnon started, why we need to take it seriously and how the internet—and big technology platforms—have allowed the theory to spread.

“What if J. Edgar Hoover Had Been a Moron?” That’s the question Lawfare’s editor-in-chief Benjamin Wittes asks in a new article about his experience learning that his tweets had been written up in an intelligence report by the Department of Homeland Security’s Office of Intelligence and Analysis. After reporting on an internal DHS document and publishing other documents to Twitter, Wittes learned that I&A had distributed intelligence reports about those tweets along with the tweets of New York Times reporter Mike Baker. After Shane Harris reported on I&A’s activities at the Washington Post, DHS announced that it was halting the practice of collecting information on journalists and the head of the office was reassigned. Quinta Jurecic discussed the bizarre story with Wittes and former Assistant Attorney General for National Security David Kris.

Last Friday the Lawfare Podcast brought you Secretary of State Mike Pompeo's full statement before the Senate Foreign Relations Committee, and his question and answer session with the senators, all with "no bull." A few days before that hearing, the Democratic staff of the Committee released its most recent oversight report titled "Diplomacy in Crisis: The Trump Administration's Decimation of the State Department." Following remarks by Ranking Member Bob Menendez, Margaret Taylor moderated a panel discussion about the report featuring three distinguished former ambassadors with close to 75 years of diplomatic experience between them—Tom Shannon, Barbara Stephenson and Bonnie Jenkins—as well as Elizabeth Shackelford, who in 2017 resigned her career post in protest of the Trump administration. They talked about the contents of the minority staff report, the recommendations it contains and the long-term consequences of what the report documents for America's foreign policy and national security interests.

Michel Paradis is a scholar of international law and human rights who has worked for more than a decade for the U.S. Department of Defense Military Commissions Defense Organization, where he has worked on a number of the landmark court cases to arise out of Guantanamo Bay. Most recently, he is the author of the book "Last Mission to Tokyo: The Extraordinary Story of the Doolittle Raiders and Their Final Fight for Justice." It's the story of two military commissions that arose out of the first U.S. bombing raid over Japan during World War II: One, the trial by the Japanese of a number of Americans who participated in the raid, and the other after the war, of the Japanese who conducted the first trial for their conduct of that trial. Benjamin Wittes spoke with Michel about the extraordinary history he uncovered, how he came to be interested in these cases and how they relate to the ongoing U.S. experiments with military commissions.
