Elon Musk and California Gov. Gavin Newsom escalated their war of words after the billionaire said his companies SpaceX and X would leave the state over its passage of a controversial student gender identity law.

Musk described the law, which blocks school districts from requiring teachers to notify parents about changes in a student's gender identity or sexual orientation without the child's permission, as the "final straw" and said both companies would relocate to Texas.

After the announcement, Newsom shared a screenshot on X of a 2022 Truth Social post by former President Donald Trump.
