SpaceX has moved to evacuate employees from Brazil and warned others against traveling to the country, a sign of how Elon Musk's ongoing battle against Brazil's highest court over his social-media company X is spilling out to affect some of his other businesses.

In an email late last week, SpaceX President Gwynne Shotwell advised employees not to travel to Brazil for work or pleasure, according to people familiar with the email. The space company also last week took steps to relocate from the country its small group of non-Brazilian employees there, one of the people said.
