Gov. Arnold Schwarzenegger, who outraged some Mexican-American groups last week by calling for a closed border, praised the civilian volunteer Minuteman Project for its patrols to spot illegal immigrants.
"Look, they've cut down the crossing of illegal immigrants by a huge percentage," Schwarzenegger told KFI-AM's "The John & Ken Show" on Thursday.
The Republican governor accused the federal government of failing to control the border and said it encouraged illicit crossers by giving them access to water.
"The whole system is set up to really invite people to come in here illegally, and that has to stop," he said.
The Minuteman Project involves hundreds of volunteers, some of them armed, who have been patrolling the Mexico-Arizona border since April 1 to document and report illegal crossings.
