First endorsement in 48 years? I'm pretty sure this qualifies as an endorsement:
> As detailed in the Climate Action Plan, President Obama is committed to using every appropriate tool to combat climate change. Nuclear power, which in 2014 generated about 60 percent of carbon-free electricity in the United States, continues to play a major role in efforts to reduce carbon emissions from the power sector. As America leads the global transition to a low-carbon economy, the continued development of new and advanced nuclear technologies along with support for currently operating nuclear power plants is an important component of our clean energy strategy. Investing in the safe and secure development of nuclear power also helps advance other vital policy objectives in the national interest, such as maintaining economic competitiveness and job creation, as well as enhancing nuclear nonproliferation efforts, nuclear safety and security, and energy security.

> The President’s FY 2016 Budget includes more than $900 million for the Department of Energy (DOE) to support the U.S. civilian nuclear energy sector by leading federal research, development, and demonstration efforts in nuclear energy technologies, ranging from power generation, safety, hybrid energy systems, and security technologies, among other things. DOE also supports the deployment of these technologies with $12.5 billion in remaining loan guarantee authority for advanced nuclear projects through Title 17. DOE’s investments in nuclear energy help secure the three strategic objectives that are foundational to our nation’s energy system: energy security, economic competitiveness, and environmental responsibility.
