Musk signaled he was open to a truce, and White House officials reportedly scheduled a call with him.

The blowup could have a payoff for Boeing in three areas: its struggling Starliner crew capsule program; the embattled Artemis moon landing program, for which Boeing produces giant rockets; and potentially United Launch Alliance, its rocket joint venture with Lockheed Martin.

Trump’s tariffs are intended to bring jobs back to the U.S. and benefit small businesses, but a new report from the National Federation of Independent Business shows they’ve
