I am not aware of any legislative obligations to publish lists of names of people on whose behalf other governments are actively engaged.
I would note this: Many of you are probably familiar with the comprehensive human rights reports published every year by the State Department. These detail human rights situations in countries around the world. Based on my observations and my reading of many of those reports, I am not aware—other than emblematic cases, perhaps, which are broad public knowledge—of any detailed information on specific cases being acted upon.
