We obtained internal data showing the Trump administration knew that at least 197 of the men had not been convicted of crimes in the U.S. — and that only six had been convicted of violent offenses. We identified fewer than a dozen additional convictions, both for crimes committed in the U.S. and abroad, that were not reflected in the government data.

Nearly half of the men, or 118, were whisked out of the country while in the middle of their immigration cases, which should have protected them from deportation. Some were only days away from a final hearing.
