"Crenshaw was in combat during his time as a U.S. Navy SEAL. He served multiple deployments overseas, including in Iraq and Afghanistan. On his third deployment in 2012, while on a mission in Helmand Province, Afghanistan, he was severely injured when an IED detonated near him. The blast destroyed his right eye and badly damaged his left, though he later regained sight in his left eye after extensive medical treatment."
Sounds like it could be brain damage and/or severe PTSD. He should not be in Congress.
I’ve always thought he was pretending to be Lieutenant Dan from the 90s film Forrest Gump.
