SAN DIEGO (AP) – Attorney General Jeff Sessions has ordered a “zero tolerance” policy aimed at people entering the United States illegally for the first time on the Mexican border.

His directive Friday tells federal prosecutors in border states to put more emphasis on charging people with illegal entry, which has historically been treated as a misdemeanor offense for those with few or no previous encounters with border authorities. Smugglers and repeat offenders are usually charged with more serious crimes.

Sessions tells prosecutors to ask for additional resources if needed to prosecute cases. As a model, he points to a Border Patrol effort launched in 2005 that typically resulted in a conviction and short time in jail.
