we first learned about these strange attacks, these strange symptoms with u.s. personnel in accounting. cbs radio first to report american diplomats were reporting incidents which caused a variety of physical symptoms. super vague in the initial reporting that was very unclear what types of incidents were happening here. the state department was totally bafflingly vague and confusing on the subject. we now thanks to good reporting on the subject, we now know it's as scary and weird as it seemed before we knew the details. we now know there are 21 medically confirmed cases, some involve permanent hearing loss or traumatic brain injury. yesterday the associated press published some scary details on the attacks. let me read to you straight from the a.p. story. quote, the blaring, grinding noise jolted the american diplomat from his bed in a havana hotel. he moved just a few feet and there was silence.
