AP - Billionaire businessman Donald Trump acknowledges he probably needs to act more presidential and says he'll do so "pretty soon."
The often brash Trump tells "Fox News Sunday," ''I think I'll be very presidential at the appropriate time. Right now, I'm fighting for my life."
Trump has chalked up his second win in a row, duplicating his success in New Hampshire with a win in South Carolina on Saturday. His victory comes after a week in which he threatened to sue one rival, accused former President George W. Bush of lying about the Iraq war and even tussled with Pope Francis on immigration.
Trump says he "can act as presidential as anybody that's ever been president other than the great Abraham Lincoln." He says Lincoln was hard to beat.
