Cable news	Testing	test, travel, important, medical, fact, economic, pence, risk	One you have to be clear honest and transparent about the scope of the virus and infection. And you need to test to do so. We are failing to do that miserably right now. Yesterday finally nearly a week into his tenure overseeing the response to coronavirus Vice President Mike Pence said the U.S. plans to send out 2500 testing kits by the end of the week to test up to 1.25 million people. That’s a start but it is still going to take too long to get that testing capacity up and running nationwide. And when the tests do deploy case numbers in this country will spike which will freak people out. They should be. I don’t think you’re calling for the testing of 320 million people. You’re saying that people who believe they may have been exposed to the virus need to know whether or not they have it and you can’t find tests for those people

It’s actually Donald Trump’s because there are some things you can’t lie and spin your way through above all something like a virus which is out of control

The disease has killed almost 200 people in Italy in just the past 24 hours. Markets are responding to this. The Dow dropped almost six percent today But what I want to talk to you about today just for a moment or two is that we would like the country to realize that as a nation we can’t be doing the kinds of things we were doing a few months ago. That it doesn’t matter if you’re in a state that has no cases or one case you have to start taking seriously what you can do now that if and when the infections will come and they will come sorry to say sad to say they will.
