WASHINGTON (AP) — Homeland Security Secretary Jeh Johnson is weighing limiting deportations of immigrants living in the U.S. illegally who don’t have serious criminal records, according to two people with knowledge of his deliberations.

The change, if adopted following an ongoing review ordered by President Barack Obama, could shield tens of thousands of immigrants now removed each year solely because they committed repeat immigration violations, such as re-entering the country illegally after having been deported, failing to comply with a deportation order or missing an immigration court date.
