Washington (CNN) President Donald Trump's administration has ordered a freeze on some Environmental Protection Agency grants and contracts to states, as the department braces for more dramatic changes going forward.

"This is exactly what we were concerned about in the beginning," said Wenonah Hauter, head of Food & Water Watch. "It's a war on the EPA."

The EPA under a Donald Trump presidency will be everything he promised, according to an EPA action plan drafted by Myron Ebell, a member of Trump's transition team who's also a director at the libertarian think tank Competitive Enterprise Institute.

A "wish list" for the EPA targets regulations such as carbon emission rules that limit the amount of greenhouse gases allowed from power plants, and chopping $193 million in climate programs.

Marlo Lewis of CEI says the changes are welcome.
