The agency’s planned repeal of a cornerstone of US climate rules is part of an aggressive deregulatory agenda whose effects on the environment will outlast the president.

President Trump is expected to make an announcement surrounding the Environmental Protection Agency's "endangerment" finding. CBS News' David Schechter reports.

The Environmental Protection Agency is eliminating a Clean Air Act finding from 2009 that is the basis for much of the federal government's actions to rein in climate change.

EPA Administrator Lee Zeldin officially revoked the endangerment finding, in a huge blow to U.S. efforts to fight climate change.
