Vice President Kamala Harris walked a scrubby stretch along the U.S.-Mexico border on Friday and called for further tightening of asylum restrictions as she sought to project a tougher stance on illegal migration and address one of her biggest vulnerabilities in the November election. Harris’ push to further restrict asylum claims moves beyond President Joe Biden’s policy on an issue where her rival, former President Donald Trump, has an edge with voters. She balanced tough talk on policing the border with calls for a better way to welcome immigrants legally. “I reject the false choice that suggests we must choose either between securing our border and creating a system that is orderly, safe and humane,” Harris said. “We can and we must do both.” Before this trip, Harris has largely shied away from the topic of immigration and has given few details about what she would do if elected. That's a reflection of how the issue has become such a controversial topic for the Biden administration.
