Immigration and Customs Enforcement officers — often dressed in plainclothes — are now arresting immigrants at courthouses nationwide, sometimes moments after their hearings end. Why it matters: The courthouse crackdown is part of a sweeping Trump administration effort to fast-track removals and increase the number of deportations this year — a strategy that's dramatically expanding who gets targeted and how.

The arrests, which began in San Diego in late May, are happening across the country. Lawyers say it’s an unprecedented effort by ICE to deport immigrants through a fast-track deportation process known as “expedited removal.

The Trump administration has a novel strategy to boost arrests and reduce courts’ backlog: dismissing people’s immigration cases and immediately arresting them.
