By Hannah Jewell and Jamie Ross Listen to this briefing Good morning. It’s Friday, Jan. 31, and this history of commercial plane crashes — and how they changed the way we fly — is worth reading today. Let’s start with the latest from D.C. We’re learning more about the deadly D.C. plane crash. The latest: The control tower at Reagan National Airport was understaffed Wednesday night. Listen to air traffic control in this audio, and see a visual reconstruction of the crash here. The victims: Sixty-seven people died in the collision, including competitive figure skaters, service members and children. Family members shared memories of those lost. Read this story          President Donald Trump baselessly blamed a diversity program for the crash. What to know: Without evidence, Trump said Democrats and diversity were to blame. He actually launched an air controller diversity program in 2019 — we fact-checked him here. In other Trump news: Multiple FBI officials were told to leave their jobs or be fired. And an official tried to undo Trump’s purge at USAID — then he was purged, too. Are you a federal worker? Think twice about Trump’s resignation offer. Read this story          A trio of high-profile confirmation hearings took place yesterday. What happened? Senators grilled Trump’s intelligence pick Tulsi Gabbard about Edward Snowden and Syria. FBI pick Kash Patel tried to distance himself from Jan. 6 rioters. What else to know: Health secretary nominee Robert F. Kennedy Jr. repeatedly contradicted past statements in his second hearing. Find all our takeaways from the busy day here. Read this story          Meta CEO Mark Zuckerberg said the company is still committed to diversity. This week: Zuckerberg tried to reassure his liberal-leaning workforce following some dramatic policy shifts, including ending Meta’s diversity and fact-checking programs. In other tech news: Companies are trying to reassure investors of their AI capabilities after Chinese chatbot DeepSeek’s overnight success wiped a trillion dollars from their value. What else to know: AI’s use in art and movies got a boost this week. Read this story          Uganda announced a new outbreak of Ebola. The details: A 32-year-old nurse died of the virus in Kampala, the East African nation’s capital, officials said yesterday. He had 44 close contacts, who are being traced. Digging deeper: Uganda’s last outbreak, in 2022, killed 55 people. Ebola is spread through direct contact with body fluids of an infected person. There is an effective vaccine. Read this story          The FDA approved a new, non-opioid painkiller yesterday. What is it? Journavx, whose active ingredient is suzetrigine. It’s the first novel pain drug to win authorization in more than 20 years. Its maker says it’s not addictive. Why it matters: It could be a tool to fight the deadly opioid epidemic. It intercepts pain signals before they reach the spinal cord, rather than acting directly on the brain.
