Surgeon general: new vaccine policies "part of a long tradition"

• The measures are likely to face legal challenges from Republican governors, who were quick to express their disdain with the administration's plan.
• Murthy also appeared on ABC's "This Week," where he called Biden's new policies "an appropriate legal measure."

What they're saying: "One of the things that we cannot afford to do during this pandemic is allow the COVID-19 experience to turn us against each other. Our enemy is the virus; it is not each other," Murthy told "Meet the Press" host Chuck Todd.

• "We've got to use every lever we have in order to fight this pandemic," he added.
• "In the face of Delta, we've got to move to the next phase of that response, and that involves focusing not just on expanding the vaccination efforts through a combination of mandates and access, but it also involves focusing on increasing our testing capacity."
