In February, a massive cyberattack nearly brought down the entire U.S. health system. Doctors are still reeling, and many patients don’t even know their data has been exposed. Today, Dan Diamond traces what went wrong and the new scrutiny in Congress.

Even if UnitedHealthcare isn’t your health insurer, the company has probably interacted with you or your data in some way. UnitedHealth Group is both the nation’s largest insurer and its largest employer of physicians. It owns pharmacies and home health agencies. One of its subsidiaries, Change Healthcare, processes more than 40 percent of the country’s medical claims, acting as a kind of “information superhighway,” explains the Post’s national health reporter, Dan Diamond.

In February, hackers broke into that system and led to what is being described as the largest cyberattack ever in American health care. Behind the scenes, the attack froze health payments and compromised patient information. It spread pain across doctors and hospitals nationwide, especially in rural communities. It’s still unclear how many people have been impacted, and the breach has yet to be fully resolved.

The chaos and fallout brought UnitedHealth Group’s CEO, Andrew Witty, to testify this week before Congress for the first time in more than 15 years. During separate House and Senate committee hearings, representatives grilled Witty on why basic security safeguards were lacking and, more broadly, whether UnitedHealth Group might have become too big, raising bigger questions about how U.S. health care operates.

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.

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.

India is rising as a competitive global power. It is also joining a club of nations that aggressively target dissidents on foreign soil. Today on “Post Reports,” we dive into India’s assassination plots.

It was a split-screen moment: As the Biden administration hosted a White House state dinner for Indian Prime Minister Narendra Modi in 2022, an officer in India’s intelligence service was relaying instructions to a team hired to kill one of Modi’s most vocal critics in the United States. The assassination plot was part of several repressive acts targeting Indian diaspora populations in Asia, Europe and North America, according to officials in the United States and in India.

Greg Miller, a Washington Post investigative foreign correspondent, breaks down how a team of Post reporters have probed a global surge in aggression against dissident groups.

Amid shifting geopolitical forces, Miller explains how the United States and other Western governments have struggled to stem this repressive tide. India, for example, has faced few consequences for its use of violence against dissident groups, in part because the United States and its allies want closer ties with India in a new era of competition with China.
