President-elect Donald Trump will attend a SpaceX Starship launch Tuesday. The rocket company is owned by Trump booster Elon Musk.

The president-elect’s appearance in Texas demonstrates the growing closeness between the two billionaires, and Mr. Musk’s increasing influence in Mr. Trump’s orbit.

Donald Trump went to Texas to watch a spaceship launch tower catch a moving rocket booster with the tenderness of a parent cradling their newborn baby, but all he got instead was 33 rocket engines crashing into the ocean.
