RNC Roll Call Begins With Slight Possibility of Fireworks

CLEVELAND, Ohio -- The roll call vote to select Donald Trump as the Republican nominee was underway Tuesday night -- with a slight possibility of fireworks on the floor, even though they won't change the outcome.

Any vocal dissent from the floor could be embarrassing for Trump and signal a lack of unity in the party. But in ABC News' conversations with delegates and leaders of efforts to go rogue, it seemed some delegates had backed out of their intent to put up a fight tonight.

The convention secretary will go one-by-one through the list of states alphabetically as the chairs of each delegation will briefly tout their state before announcing their state's vote total.
