President Biden's acting Attorney General Monty Wilkinson issued a memo on Tuesday to revoke the Trump administration's "zero tolerance" immigration policy, which separated thousands of migrant children from their families at the U.S.-Mexico border, AP first reported.

Driving the news: A recent report by Justice Department Inspector General Michael Horowitz emphasized the internal chaos at the agency over the implementation of the policy, which resulted in 545 parents separated from their children as of October 2020.

What they're saying: “Consistent with this longstanding principle of making individualized assessments in criminal cases, I am rescinding — effective immediately — the policy directive,” Wilkinson wrote in the memo, per AP.

• He added that the DOJ's standards have “long emphasized that decisions about bringing criminal charges should involve not only a determination that a federal offense has been committed and that the admissible evidence will probably be sufficient to obtain and sustain a conviction, but should also take into account other individualized factors, including personal circumstances and criminal history, the seriousness of the offense, and the probable sentence or other consequences that would result from a conviction.”
