Most Republicans applauded President Donald Trump's decision to pull out of the climate accord.

"I applaud President Trump and his administration for dealing yet another significant blow to the Obama administration's assault on domestic energy production and jobs," said Sen. Mitch McConnell of Kentucky, the majority leader.

House Speaker Paul Ryan, R-Wis., called the climate agreement "simply a raw deal for America."

"It would have driven up the cost of energy, hitting middle-class and low-income Americans the hardest," he said.

Sen. John Barrasso, R-Wyo., chairman of the Senate Committee on Environment and Public Works, said, "The Paris climate agreement set unworkable targets that put America at a competitive disadvantage with other countries and would have raised energy costs for working families."

But Sen. Susan Collins, R-Maine, wrote on Twitter, "Climate change requires a global approach. I'm disappointed in the President's decision."
