The Trump administration announced on Thursday new oil drilling off the California and Florida coasts for the first time in decades, advancing a project that critics say could harm coastal communities and ecosystems, as President Donald Trump seeks to expand U.S. oil production.

The oil industry has been seeking access to new offshore areas as a way to boost U.S. energy security and jobs. The federal government has not allowed drilling in federal waters in the eastern Gulf of Mexico, which includes offshore Florida and part of offshore Alabama, since 1995, because of concerns about oil spills. California has some offshore oil rigs, but there has been no new leasing in federal waters since the mid-1980s.

Since taking office for a second time in January, Trump has systematically reversed former President Joe Biden's focus on slowing climate change to pursue what the Republican calls U.S. "energy dominance" in the global market. Trump, who recently called climate change "the greatest con job ever perpetrated on the world," created a National Energy Dominance Council and directed it to move quickly to drive up already record-high U.S. energy production, particularly fossil fuels such as oil, coal and natural gas.

Meanwhile, Trump's administration has blocked renewable energy sources such as offshore wind and canceled billions of dollars in grants that supported hundreds of clean energy projects across the country.

California Gov. Gavin Newsom pronounced the idea "dead on arrival" in a social media post. The proposal is also likely to draw bipartisan opposition in Florida. Tourism and access to clean beaches are key parts of the economy in both states.
