California Gov. Jerry Brown is dismissing the President Trump's method of pushing agenda items on Twitter.

"You can't fight reality with a tweet," Brown told Politico.

The Democrat was in the middle of a conversation about Trump's reported decision to remove the U.S. from the Paris climate agreement. He hasn't made an official statement yet, but Trump tweeted late Thursday that he will make an announcement on the Paris agreement at 3 p.m. ET on Thursday.

Brown argues Trump's opposition to the climate accord is not shared by some Republicans and that momentum is not in Trump's favor.

"This current departure from reality in Washington will be very short-lived, that I promise you," Brown said. "I've spoken with Republicans here in the Legislature, and they're beginning to get very serious about climate action, so the momentum is all the other way. And I think Trump, paradoxically, is giving climate denial such a bad name that he's actually building the very movement that he is [purporting] to undermine."
