New from @CBSNews: Some of the highest-ranking officials in the U.S. military were subjected to polygraph tests as part of a sweeping leak probe after highly sensitive classified details about the nation's stockpiles of sophisticated weapons were reported in the media. President Trump was furious about the leaks. A very small set of people had access to the classified details on the munitions, and there was concern about whether anyone could potentially be acting as a foreign intelligence asset, one of the sources said. Polygraph tests are often a part of the routine cadence for top military and civilian officials, but the mass volume of people who were pulled in for testing in this case was extremely rare. @JimLaPorta @ellee_watson and me: cbsnews.com/news/top-militar…

NEWS via @CBSNews: An Iranian drone attack in Kuwait that killed U.S. service members in the early hours of the war with Iran was more severe than previously known, with dozens suffering injuries that included brain trauma, shrapnel trauma and burns, per sources. More than 30 remained in hospitals yday with battle injuries — one at Brooke Army Medical Center in San Antonio, 12 at Walter Reed, and about 25 at Landstuhl in Germany, sources said.  Of those, about 20 arrived on a C-17 military transport aircraft at Landstuhl on Tuesday with injuries the military designated as “urgent” and requiring evacuation. More than 100 medical personnel were sent to Landstuhl to assist. Report here from @ellee_watson @JimLaPorta and me. cbsnews.com/news/strike-in-k…
