President Trump has gotten some major allies in his emissions fight with the state of California.

According to The Daily Caller:

General Motors, Fiat Chrysler and Toyota sided with the Trump administration in a battle over emissions against the state of California.

The Trump administration proposed to lower emissions standards set during the Obama administration, according to The New York Times. California responded to the proposal by announcing the state would continue to enforce the Obama administration laws on fuel economy standards for automobiles.

Led by the Association of Global Automakers, the three companies announced Monday they are siding with the Trump administration, a move that pits them against Ford and Honda, which reached a deal to follow California’s stricter emissions standards earlier in 2019, The NYT reported.

The automakers siding with Trump said the federal government, rather than California, has the primary authority to set fuel emission standards.

Trump has pointed to the removal of the waiver as a catalyst for making cars safer and less expensive.
