in whichok at the deal the president was able to get a much better deal for the united states, we have made great progress on nafta. we hope to have great progress on trade negotiations with china. president said it came out with this journey coming up. rates and levels nobody has ever seen before. said it came out with this journey coming up. >> i believe it was the l.a. times. there is also a well documented fact that a lot of the people believe up to 80% in recent years of women that are making that journey have been raped. the president is saying it is simply unacceptable. saying the drug smugglers, the traffickers, this is something that has been in recent years. we know there could be some fluctuation. change.s to is the firstdent time -- frankly we shouldn't be in this situation. actions longe before today. and some really courageous and bold action might president trump has done. step?n is the next do you want them to come forward and negotiate? >> we want to be able to stopiate, we want to illegal trade practices. being a huge detriment to the businesses. the dow is down nearl

data, and they did sign on to the act that requires online political disclosure for advertising on whichok, google, etc., they had been resisting, frankly, this kind of disclosure , for years until now. so i do think maybe he'lle get a -- maybe he will get a friendly reception after the last few days, with the changes they are making. but definitely they will face dozens of lawmakers who will have very tough questions that facebook still doesn't have good answers for. host: the first appearance by mark zuckerberg is tuesday, at a joint judiciary and commerce committee hearing. what is the focus on the senate side, is it any different than the house, and who should we watch for? teven: there is upwards of 30 senators that are going to be at this massive hearing with judiciary and commerce. think from democrats, you are going to hear a lot of questions about russia and the company's failure to pick up on and stop to attempts by russia influence americans ahead of the election in 2016. be a lot ofng to concerns about what they are doing, whether they are ready to stop similar efforts heading
