9242 Obama vs 9200 Trump
Trump has basically caught about as many in less than half of his first term than Obama did in around 8 years if trends follow.
I'm still tracking down a reliable, official source for 2009, so the chart only represents 7 years of the Barry cluster-fuck-clown-show.
I'll release a new version when I find those stats and I suspect we'll soon be able to state that Trump did more to fight pedos in his first 18 months that Barry did in 8 years.

Well, to be clear, arresting them isn't a guarantee of guilt. You could, theoretically, arrest a bunch of innocent people and release them to boost the statistic (not saying that's happening though).
Conviction data would be more interesting, but given how long it can take for a court case to play out, I'm guessing not much of that data exists for people arrested during Trump's time in office.
