Among the many questions Facebook CEO Mark Zuckerberg wrestled with as he testified before Congress Tuesday and Wednesday was one of a more existential nature: What, exactly, is Facebook?

Sen. Dan Sullivan (R-Alaska) asked Zuckerberg whether the social networking website was a tech company or a publisher.

On Monday, Facebook began notifying the up to 87 million users whose information may have been compromised and given to Cambridge Analytica. As Facebook CEO Mark Zuckerberg testifies before Congress Tuesday and Wednesday, lawmakers like Sen. Bill Nelson have raised privacy concerns.

Today, the Chinese government announced tariffs on 128 American products, including food. Pork will be taxed 25 percent, and wine, dried fruit, and nuts are now subject to a 15 percent duty.

The announcement comes in response to the tariffs President Trump recently imposed on steel and aluminum. Trade officials from each country are negotiating, and it's not yet clear how long the duties will be in effect, or what the lasting impact will be for American producers and growers.
