HONOLULU (AP) — President Barack Obama has vetoed two measures that would have blocked steps that his administration is taking to address climate change.
One would have nullified carbon pollution standards set by the Environmental Protection Agency. The second would have voided a set of national standards designed to reduce the amount of greenhouse gas pollution from existing power plants.
In a letter notifying Congress of his decision, Obama says climate change is a "profound threat" that must be addressed.
Some Republican lawmakers and presidential candidates scoff at the climate science.
Obama has made addressing climate change a priority. He recently praised a new international climate agreement reached at a Paris conference and credited his administration as being a driving force behind the deal.
He rejected the measures through a rare "pocket veto," intended to be used when Congress has adjourned, as it did Friday for the year. A pocket vote essentially takes effect when the president fails to sign a bill within 10 days.
