A law enforcement underwater dive team arrived at a nature reserve in Florida as the search for Brian Laundrie intensifies. Investigators are trying to piece together what happened to Gabby Petito, the 22-year-old whose remains were found near a campsite in Wyoming's Bridger-Teton National Forest. The coroner made an initial determination that she died by homicide. John Walsh is the host of “In Pursuit with John Walsh” on Investigation Discovery and is a child safety advocate after his own son was abducted and murdered 40 years ago. He joins AC360 to discuss where he thinks Laundrie is hiding and who he thinks helped him. Plus, President Biden is racing to unify moderate and progressive House Democrats as a key infrastructure vote is just days away. Evan Osnos is the author of “Joe Biden: The Life, the Run, and What Matters Now.” He tells AC360 Biden knew he was inheriting a country that had “fundamental fissures.”
