Super PACs offer $1.5M for Cruz-Trump debate

Two super PACs supporting Sen. Ted Cruz's presidential campaign are offering to donate $1.5 million to charities that help veterans if Donald Trump will debate Cruz head-to-head before the Iowa caucuses.
The political action committees, Keep the Promise I and II, are proposing a one-hour debate to be held in Iowa on or before Jan. 31, the day before the caucuses, with a moderator chosen by the candidates.
