Megafire-linked flood risk at Grand Canyon rises as Driscoll resigns and Massachusetts primaries loom

The National Park Service warned of elevated flood risk at the Grand Canyon after the Dragon Bravo megafire, with two deaths reported and the fire’s role in the floods still unclear, highlighting climate‑linked hazards. In Massachusetts politics, primaries spotlight a generational split among Democrats, pitting older incumbents like Sen. Ed Markey against younger challengers such as Rep. Seth Moulton and testing Biden/Harris support. Separately, Army Secretary Dan Driscoll has submitted his resignation, joining a wave of high‑level DoD departures.
