Tucker Carlson debated a Bay Area radio host over his support for Gov. Jerry Brown's (D-Calif.) clean energy accord with China.
Brown previously slammed President Trump's decision to pull out of the Paris accord, warning that "people will die, habitats will be destroyed and the seas will rise."
Carlson pointed out that it is unconstitutional for a state to usurp federal powers and act on its own when dealing with other nations.
KGO's Ethan Bearman said the agreement signed with President Xi Jinping is nonbinding and therefore still legal.
Carlson still doubted the legality of Brown's actions, noting he "grew up in California when it was a state."
Bearman said it was wise for California to leverage its economy with China's.
"California doesn't have the right to do that," Carlson said. "[It's] so high on its own fumes it lost sight of [that]."
He asked whether Brown might take the next step toward antagonizing Washington by "taking over Camp Pendleton and declare war on Mexico."
