The National Transportation Safety Board and Federal Aviation Administration are investigating why airport traffic wasn’t halted during Marine One’s departure with President Trump on Tuesday. Despite a previous ban on non-essential helicopter flights at Reagan National Airport, the Marine Corps reported the flight as “routine.”

Former Michigan health official Abdul El-Sayed won the Democratic Senate primary, defeating Rep. Haley Stevens. El-Sayed’s leftist platform gained endorsements from prominent progressives, positioning him for a general election contest against Republican Mike Rogers, who ran unopposed in his primary.
