Donald Trump is closer than ever to clinching the Republican nomination on the first ballot. Here's a look at claims he made over about 16 hours.
On Kasich
Trump: "As soon as Kasich gets hit with the first negative ad — he's had none — bing, that's the end of that."
The facts: To say no ads have attacked Gov. John Kasich is not true. In fact, his own campaign has run an ad attacking Kasich. Outside groups have spent nearly $5 million opposing Kasich.
On NATO
Trump: "I gave a great answer. … I said it's obsolete and too many people are getting a free ride because we're funding 72, 73 percent of NATO."
The facts: The United States pays 22 percent of the cost of NATO in direct funding. He begins to have a point when talking about indirect spending on NATO: The U.S. defense expenditure represents about 72 percent of the spending on defense by all countries that are NATO members. U.S. defense spending far exceeds the spending of other NATO members, and that imbalance is driven by the United States' role as a world power. It makes little sense to count defense spending in Asia as part of "NATO funding."
On immigration
Trump: "If you look at what's going on with immigration, and just look at the record numbers of people right now that are pouring across the borders of this country."
The facts: The illegal immigration flow across the U.S.-Mexico border has been declining for years. Apprehensions of people from Mexico have decreased to 188,122 in fiscal 2015, from 1.6 million in fiscal 2000.
On the Iraq war
George Stephanopoulos: "You were for it, though, before you were against it."
