Ahead of the tight Iowa caucuses, U.S. Republican presidential candidate Donald Trump vows to step-up fight on Islamic State militants, saying, ''we don't know who we're fighting for.'' Rough Cut (no reporter narration).
ROUGH CUT (NO REPORTER NARRATION) U.S. Republican Presidential Candidates in Cedar Rapids, Iowa on Monday told supporters at a rally ahead of the Iowa caucuses that if he were elected to the U.S. Presidency, that the fight on Islamic State fighters in Syria and Iraq would look different. "We don't know who we're fighting for, we don't know how to fight anymore. We have generals that go on television. They're always constantly on television. I don't want my generals going on television," Trump said. I saw one of them who's retiring, they said, 'What do you think of ISIS?' 'Oh, they're very tough, they're very tough.' I said, 'What's he doing? What's he doing?' You know, you're talking about 30,000 people… it just emboldens them to do what they want to do," Trump added. The long and sometimes arcane ritual of electing the next U.S. president begins on Monday in more than 1,100 schools, churches and libraries across Iowa, a state that wields political influence far greater than its small size. After more than a year of up-close and personal evaluation of the candidates, Iowans will gather with their neighbors on what promises to be a cold wintry night to kick off the state-by-state process of picking the Republican and Democratic nominees for the Nov. 8 presidential election.
