Transcript for What to expect from G-7 summit
president trump is set to depart for Europe today and a tense summit with America's closest allies at the g7 summit. The last two were steeped in controversy. That seems likely this time too. Let's bring in Jon Karl and, Jon, the president's already shaking up the schedule with his call for a special meeting on the global economy. Reporter: A meeting that will happen Sunday morning, George. It's likely to be a contentious one. Our European allies are especially concerned with the president's actions on trade, the tariffs I has already imposed and his threat to impose more. He's threatened to impose tariffs on everything from cheese to French wine. The president set the tone yesterday when I asked about warning signs about the U.S. Economy and he said that the U.S. Is doing great economically, it's the rest of the world that's the problem. That's what the president told you yesterday but there is some concern behind the scenes at the white house about a potential slowdown, a recession as we head into the election next year and have seen the president and his team all over the what happen on what to do about it. Reporter: There's no question about that, George. The U.S. Economy continues to grow and publicly you hear from the president's closest advisers that they think that the economic indicators are all still strong. But you can see the back and forth about wlornts there needs to be an economic boost, the back and forth about doing a payroll tax cut. Yesterday the president's top economic adviser said there will be no temporary tax cut put in place. But that the president may campaign on a new tax cut in the upcoming election. The president backed off those calls for background checks on guns earlier but a top Democrat, top gun control advocate in the senate is not giving up hope. Reporter: This is really interesting. The president says that he had a meeting about gun issues last night at the white house. He's looking into bipartisan measures and Chris Murphy, one of the top Democrats in the senate on the gun issue said that he talked to the white house yesterday and look at this. He says they have not walked away from improving background checks. I am skeptical we can reach consensus but I'm willing to stay at the table over the next few weeks. So it seems like there is some movement. On this issue the president has been all over the map. Yep, he sure has. Jon Karl, thanks very much.
