DR. MARC SIEGEL (FOX NEWS MEDICAL CONTRIBUTOR): So I think that this will have a huge impact on our economy and I'm actually wondering whether this could have something to do with President Trump this week saying that foreign workers with visas are not allowed into the country.
Could this be retaliatory? Possibly. Could it be public health? Whatever it is, it is not the tone they sounded back in March, when they were horrified at our travel ban, at a time when thousands and thousands of cases were coming here. So I have a message for the European Union tonight. How about remembering what we did for you in the middle of the 20th century?
