Donald Trump just "poked the bear," and now he's "terrified," according to a longtime thorn in the president's side.

Adam Schiff, one of California's two senators, the lead prosecutor in Trump's first impeachment trial, and a January 6th Committee member, called Trump's attacks on him a "badge of honor" in a message to supporters on Sunday.

"Unless you are part of the MAGA world, in which case you may recognize me from Trump's frequent attacks and name calling like 'sleazebag,' 'traitor,' or more recently, 'one of the true lowlifes in the history of politics in America,'" the senator wrote. "A true badge of honor."

Schiff went on to call out Trump for purported attacks on democracy.

"Trump is at it again. But this time his attacks aren't just against me, he's going after our very democracy," he wrote. "You see, Trump is terrified of losing his majority in the midterms. And his solution isn't to end his pointless tariff wars, stop the indiscriminate masked ICE raids, or rethink his deeply unpopular Big Ugly Bill. It's to demand Republicans in Texas redraw their Congressional maps."

Schiff continued, saying, "It's sad. It's tragic. But if Texas acts, California must respond."

"I was proud to stand with our Governor, Gavin Newsom, as he introduced California's Election Rigging Response Act," he then added. "The people of our state will vote this November. If we win, we'll nullify anything Texas does. If we lose... then Trump may very well have two more years of unchecked power."

The lawmaker concluded, "Donald Trump has poked the bear. It's time to fight back."
