Trump: Why did Newsom sign bill making asking for voter ID illegal

Trump says there is no conceivable reason why Newscum signed a voting bill that ensures you're not allowed to ask for voter ID other than that they plan on cheating. He says the Democrat National convention enforces ID but not California's voting system. Why?

"He signed a bill that you're not even allowed to ask for voter ID...You have ID for everybody. The Democrats had ID when they had their convention, a friend of mine couldn't get in... He said he doesn't have the proper credentials. They want voter ID. They had a strong ID. They had an ID that you had to wear like a prisoner wears you know the number.
It was like his big card with a picture and everything over their tie. So they have it for the Democrat National Convention right? But they don't wanna have it for the vote. But Gavin Newscum signed a thing that was incredible. He signed a bill that if you ask somebody for identification having to do with voting. I think you've committed a crime.
Okay. Now there's only one reason that happens: Because they wanna cheat. There's no other reason. There's no conceivable reason."
