U.S. Senator Harry Reid's (D-NV) Communications Director, Adam Jentleson, put it concisely with that Tweet above, in response to a Washington Examiner article.
Even as Minority Leader in a Republican majority Senate, Reid can be counted on to block any attempt to resurrect the long-canceled high-level radioactive waste dump targeted at Yucca Mountain, Nevada, as he has done for decades, ever since the "Screw Nevada bill" was passed into law in 1987.
In 2010, President Obama zeroed out funding for the Yucca Mountain Project, and ordered the U.S. Department of Energy to withdraw the construction and operating license application.
