In this YouTube video,
in an interview with Gavin Newsom, starting at about 8:50, he lists some statistics painting California as a wonderful place with a thriving economy and tax rebates. He is then asked about net population change, specifically between California and Texas. He replies that California has lost about 182 thousand people.
He then goes on to say there are two studies of this population loss that have been done recently and that they give the primary reason as Trump administration visa policies.
What is Newsom saying about the Trump visa policy? How is he claiming that this produced net migration out of California?
