The broadcast from Charlotte will be the third time in as many weeks that O’Malley has appeared on a national Sunday morning talk show.

Last week, O’Malley blasted Mitt Romney’s Republican Party as one of “exclusion,” saying on CNN’s “State of the Union” that the GOP is hostile to the rights of immigrants and women. Republicans later accused him of being divisive.

The week before, O’Malley, the chairman of the Democratic Governors Association, tangled on NBC’s “Meet the Press” with Virginia Gov. Robert F. McDonnell (R), who leads his party’s governors group.
