SENATE VOTES DOWN CLIMATE RULES: The Senate voted Tuesday to overturn President Obama's carbon dioxide limits for power plants, the key piece of his climate change agenda.

In a pair of votes, senators passed resolutions under the Congressional Review Act to stop the regulations for existing power plants and for new ones.

Less than two weeks before the United Nations climate deal negotiations in Paris, the GOP wanted to send a strong message that they disagree with the rules, which represent the main pillar of what Obama is contributing to the international deal.
