Schwarzenegger added that he's "sick and exhausted of these fake conservatives who believe in states' rights to make their own policies - as long as state policy is to pollute more".

The Trump administration Thursday pushed ahead with plans to unravel the federal government's most effective action to fight climate change - aggressive fuel economy standards aimed at getting the nation's cars and trucks to average more than 50 miles per gallon by 2025.
The EPA contended in a press release on Thursday that the current Obama-era gas mileage standards have been a factor in the rising cost of cars to an average of $35,000, which makes purchasing a new vehicle unaffordable for many Americans.More news: Guardians Of The Galaxy: Disney Has No Plans To Rehire James Gunn
The EPA's Scientific Advisory Board said in June that it would review a number of the changes made under former Administrator Scott Pruitt, including the plan to reduce vehicle efficiency standards.
Transportation experts question the reasoning behind the proposal.
Whereas under the previous rules enacted in 2012, CAFE targets would ramp up every year, the new proposal intends to keep the 2020 numbers in place through 2026.
"EPA is proposing to withdraw the waiver granted to California in 2013 for the GHG [Greenhouse Gas] and ZEV [Zero Emissions Vehicles] requirements of its Advanced Clean Cars program", the proposal says. They called the plan illegal, saying it would force motorists to pay more for gas and create more air pollution.
The proposal outlined Thursday would eliminate the sharp increase in fuel-economy requirements adopted under the Obama administration in collaboration with California. "The administration's announcement that it will relax future fuel economy (CAFE) standards is good news for consumers", Myron Ebell, director of the Competitive Enterprise Institute's Center for Energy and Environment, said in a statement.
The administration's proposal would freeze US mileage standards at 2020 levels, when the new vehicle fleet will be required to hit an average of 30 miles per gallon in real-world driving.More news: USA eyes freeze of fuel efficiency rules
The affordability argument ignores thousands of dollars of saving in fuel costs for each driver over the life of a auto, opponents of the rollbacks said.
Schwarzenegger and Trump have repeatedly criticized each other over the years, including during Trump's presidency.
"The administration's proposal goes beyond a simple rollback".
More than a dozen states follow California's standards, amounting to about 40 percent of the country's new-vehicle market.
"I hope some conservatives with a conscience will act in Washington to defend California's waiver based on these historic Republican values", he said.
"With today's release of the administration's proposals, it's time for substantive negotiations to begin", Gloria Bergquist, a spokeswoman for the Alliance of Automobile Manufacturers, said in a statement to the New York Times.More news: Google Clock now supports Spotify for alarms
'We urge California and the federal government to find a common sense solution that sets continued increases in vehicle efficiency standards while also meeting the needs of American drivers'.
