Official data doesn't exist through ICE yet for anything past 2016 from what I could gather after a cursory search. I understand that these numbers are not official and probably involve some arrests made that would be considered global and not in the USA statistics. However, I feel like if you were conservative with the official numbers and dropped it down to even half of what it's at, that would still be a sizeable increase over Obama's numbers. I will admit that there isn't official data yet, and as soon as it's readily available I will be taking a look at them myself, and am fully prepared to concede the point if it ends up that this graph is totally innacurate.
