Important questions are being raised about 9/11 as evidence surfaces in a lawsuit against the Saudi government filed by families of the people killed in the 2001 terrorist attacks.

Former National Institutes of Health Director Dr. Francis Collins, who abruptly left his NIH research lab in February, fears aggressive downsizing could impact Americans’ health.

Videos and documents turned over to the FBI in the weeks after 9/11 were not shared with its own field agents or top intelligence officials. That evidence is raising new questions for investigators.
