President Trump's secret plane switch in Turkey is putting Air Force One's security protocols and defensive capabilities in the spotlight.

Why it matters: Air Force One is the call sign for any Air Force aircraft carrying the president, meaning Trump's secret switch didn't change the designation — but it changed the plane protecting him.

The big picture: Joby's commercial aircraft business will remain focused on electric air-taxi initiatives while Resonant will become its dedicated defense unit.

The Trump administration on Monday proposed requiring food companies to tell the Food and Drug Administration when they determine ingredients are safe to eat and doing away with an oft-criticized voluntary notification program.

While analysts speculate whether Rep. Alexandria Ocasio-Cortez (D-N.Y.) will launch a Senate or presidential bid, she's planning another part of her future: having kids.

A U.S. Appeals Court said Monday that thousands of lawsuits targeting Meta Platforms, ByteDance's TikTok and other social media outlets over claims that social media is harmful and addictive can proceed.

The big picture: Tech companies have thus far skirted major regulatory scrutiny at the federal level, but the lawsuits suggest it isn't immune to heavy court penalties, which can be just as, if not more, punitive in the long term.

Danielle Thumann Severs, a longtime aide to Federal Communications Commission chairman Brendan Carr, was nominated by President Trump on Friday to fill one of the agency's two vacant seats.
