WASHINGTON, April 20 (UPI) -- Republican presidential candidate Sen. Ted Cruz is calling on his opponent, Donald Trump, to debate him ahead of Tuesday's five Mid-Atlantic primaries.
Cruz made similar challenges prior to primaries in Wisconsin and New York, which Trump ignored. Republicans have held 12 debates since last summer, though it's been more than a month — the longest stretch of the campaign so far — since the GOP field formally gathered in one place.
