US Still in Fight Against Global Warming, Pelosi Declares VOA News Democratic House Speaker Nancy Pelosi says the United States "is still i" the fight against climate change despite U.S. President Donald Trump pulling the U.S. out of the 2015 Paris agreement. Pelosi is leading a delegation of congressional Democrats to the 10-day climate conference in Madrid. She said they want to show that their presence means the U.S is not turning its back on a major threat to humanity. Pelosi said several Democratically-led House committees are working on separate parts of what would be a broad climate change plan. "This climate action plan will be an extraordinary opportunity to really invest in the clean energy economy," Pelosi said. Trump has called global warming a Chinese concocted hoax and said the 2015 Paris accord would hurt the U.S. economy Trump began officially pulling the U.S. out of the agreement last month -- a process that ends the day after the 2020 presidential election. Several Democratic candidates say they would immediately reverse Trump's withdrawal the moment they take office. .
