They didn't receive "special treatment". The guy is in jail. The King (leader) of a foreign country and an ally of ours wanted to know why this happened, and the State Department asked the attorney general of the state to explain it to them.
He got a good, all-expenses paid trip, and told them exactly why their man deserved to be in jail for 28 years.
I can understand arguing that the state department probably shouldn't spend our tax dollars on this, although that's true of MUCH of what the state department does (mollifying our allies around the world, along with most of our enemies), but I see NO REASON to attack the Colorado Attorney General for this, he stood his ground and explained how our justice system works.
I think Debbie simply misunderstood the entire event, or else she's really trying to mislead us.
It seems they might not have spent anything:
"No taxpayer dollars were spent on the trip. Suthers said his initial understanding was that the State Department was paying for the trip, but found out en route that the king was picking up the tab."
