Ambassador Jamieson Greer, Neel Kashkari, Rep. Ro Khanna

<p>This week on Face the Nation, President Trump's multi-front trade war whipsaws markets, and China fires back. What’s next as the world’s two biggest economic powers clash? Despite backing off of what he called "reciprocal tariffs" against dozens of countries, and announcing new exemptions on some key consumer products, the president is digging in on tariffs against China. We discuss what's next with U.S. Trade Representative Jamieson Greer. Then, we get a read on the broader economic impact from the president of the Federal Reserve Bank of Minneapolis, Neel Kashkari. Silicon Valley’s Democratic Congressman Ro Khanna also joins us with reaction from the tech sector. Plus , we  have a new poll on how Americans think Trump is handling the economy. And finally, an update on the measles outbreak with the former top vaccine regulator with the FDA, Dr. Peter Marks.</p>
