Via Syracuse University's TRAC:

(16 Jun 2017) The latest data from the Immigration Courts show that the number of cases waiting for a decision continues to climb. As of May 31, 2017, the Court's backlog had risen to 598,943, whereas one year ago, at the end of May 2016, the backlog stood at 492,978. This is an increase of more than 100,000 cases just in the past 12 months.

Most new cases filed in Immigration Court this fiscal year involve noncitizens charged by DHS with committing an immigration violation rather than involved in any criminal activity. For example, in only 1.7 percent of all cases were individuals charged as having committed an aggravated felony, while an additional 4.1 percent were charged with engaging in less serious criminal activity that allegedly made them deportable. Not a single person so far this year has been charged as being deportable because the individual endorsed or espoused terrorist activity, or were alleged likely to engage in terrorist activities.

So much for Trump's pledge to deport bad hombres.
