what the fukk has he spent it on, then?
The money hasn't been spent, that's what he was saying in his answer. He said a certain amount of money is being granted to each state to have the chargers built and in place by 2030. The $7.5 billion quoted was the amount authorized in the bill, not the amount that has been spent already. The money has to pass from the federal government to the states first, then the states have to make the plan for the chargers in their area and build accordingly.
If you have evidence otherwise, then provide it. But I haven't seen any evidence for the claim your tweet made.
Why are you so quick to believe lies so long as they come from a right-wing source?
