DUI, traffic tickets, simple drug possession and immigration violations made up nearly half the criminal convictions for unauthorized immigrants arrested by Immigration and Customs Enforcement last year, according to data obtained by HuffPost.

The data, obtained through the Freedom of Information Act, offer the first detailed look at ICEs shifting arrest strategy since President Donald Trump took office and scrapped his predecessors system of prioritizing the removal of people with serious criminal records or prior deportations. The statistics confirm what the less complete numbers reported by the agency last year already indicated ICE is going after people with pettier criminal records than in recent years. Roughly one-quarter of the 143,470 migrants ICE arrested last year had no criminal convictions at all, and 11 percent had no outstanding criminal charges.
