The New York Times reports:

Sergey Brin, a Google co-founder and one of the world’s richest people, is a longtime friend of Mr. Newsom, the California governor. But now, like so many other leaders in the traditionally liberal bastion of Silicon Valley, Mr. Brin has shifted to the right. With his outspokenly conservative girlfriend by his side, he has joined the ranks of tech executives courting Mr. Trump in his second term.

Last May, he attended a fund-raiser featuring Vice President JD Vance and donated nearly half a million dollars to the Republican National Committee. In September, he told the president at a White House dinner that he was “very grateful” for the administration’s support of tech companies. This March, he was named to a White House tech council and donated to a Republican candidate for governor of California who has since earned Mr. Trump’s endorsement.

Mr. Brin is particularly rattled by the proposal for a one-time, 5 percent tax on California billionaires, and has emerged as Silicon Valley’s leading combatant of the measure. To escape the tax, he moved before a Dec. 31 deadline to the Nevada side of Lake Tahoe (he now spends every other week at Google’s California headquarters, alternating with Nevada, a person familiar with the arrangement said). And he has spent $57 million to try to undercut the measure, including $9 million more disclosed on Friday.
