Ron DeSantis Was a Guantanamo Torturer?

Might be old news to you, but probable GOP presidential candidate Ron DeSantis did spend time in Guantanamo Bay as a JAG attorney. Months ago, The Empire Files interviewed a former Guantanamo detainee who swore that DeSantis' function was interviewing detainees in order to find find out how best to torture them.
Note that under the circumstances this is hearsay unless someone has corroborating anecdotes etc.
