The Trump administration’s war on electric cars continues with the halt of a national program that sends money to states to install EV charging equipment. It was the latest move by President Donald Trump to reverse Biden-era EV policies — even as those policies have personally enriched his top ally, Elon Musk.

It seems the richest man in the world may have taken things too far as Trump has reportedly stepped in to prevent a hiring of a non-US citizen.

Musk, who last year said “things that inhibit freedom of exchange or distort the market are not good,” became $12 billion poorer Monday.
