Six months after becoming speaker of the House of Representatives, Mike Johnson’s job is on the line. Today on “Post Reports,” we explore Johnson’s rise to power and his potential ouster at the hands of his Republican colleagues.Read more:Mike Johnson became House speaker following the historic ouster of Kevin McCarthy in October. After three weeks of infighting among Republicans, Johnson emerged as the only viable candidate, in part because Johnson was relatively unknown. Before becoming speaker, Johnson was best known for leading the charge to overturn the legitimate results of the 2020 election. Johnson’s short tenure has been tumultuous. Last week, Johnson helped pass a bill that provides billions of dollars in aid to Ukraine, Israel and Taiwan, over the objections of Republican colleagues. Now, in response, Rep. Marjorie Taylor Greene has vowed to introduce a motion that could see Johnson kicked out of the speakership. The House will probably take up the motion once she reintroduces it next week.Congressional reporter Marianna Sotomayor joins “Post Reports” to talk about Johnson’s politics, how he has changed since becoming speaker and the chances that Johnson could soon lose the speakership. Today’s show was produced by Peter Bresnan. It was edited by Ted Muldoon and mixed by Sean Carter. Thanks to Rachel Van Dongen.Subscribe to The Washington Post here.
