Elon Musk and his kids with Grimes have strong ties to California, singer argues to get his Texas child custody case tossed

• Claire Boucher, better known as Grimes, asked a Texas judge to throw out Elon Musk's custody case.
• Grimes said she and her 2 youngest kids moved to California more than 9 months ago.
• She also claimed Elon spends significant time in California, where courts are more likely to favor her.

The musical artist Grimes has asked a Texas judge to throw out Elon Musk's child-custody lawsuit filed last month, saying the case belongs in California, not Austin.
