WASHINGTON (Reuters) - Presumptive Republican presidential nominee Donald Trump said on Wednesday he will probably work with the Republican National Committee to raise $1 billion to beat likely Democratic rival Hillary Clinton in the Nov. 8 U.S. presidential election. “We’re going to try and raise over a billion dollars which is what’s going to be necessary. The Democrats maybe will get as high as two billion dollars,” Trump said in an interview with NBC Nightly News.
