MARGARET BRENNAN: ...Just to button up on something you referred to earlier when you talked about the increase in testing that is available to those who- who may have COVID-19. I'm sure you know that there are spikes in actual hospitalizations, people actually getting sick, particularly in Arizona and in Te- in Texas. It's not just increased testing.

WOLF: Absolutely. And again, the White House Coronavirus Task Force is on top of all of these outbreaks, looking state by state, county by county. Whether it's Arizona, Texas, Florida, a number of these states that are having hot spots, that are having those upticks. So we're surging resources, medical individuals and the like, even individuals from the Department of Homeland Security. We're surging into those to- areas to understand what is the cause of that outbreak and address that proactively.

MARGARET BRENNAN: And you don't know yet what the cause of the outbreaks in all of those Sunbelt states is?

WOLF: They're all different. They're all for various different reasons. What we see is some of the outbreaks along the southwest border in Arizona, particular parts of Texas, we have about one point five million U.S.- U.S. citizens and legal permanent residents living in Mexico, coming back over for medical treatment. So there's a variety of different reasons on why you would have different outbreaks in different states. And again, we have medical professionals, CDC has sent teams into these individual areas, the Department has as well. And we're continuing to address that.
