(CNN) Some Republican National Convention delegates broke out into a floor protest Monday afternoon after GOP officials dismissed a last-gasp effort by anti-Donald Trump groups to force an embarrassing protest vote against the presumptive presidential nominee.
A group of anti-Trump delegates submitted signatures to try to force a vote on the rules of the convention — a procedure normally done quietly at the start of each convention.
The rules were adopted by voice vote shortly after 4 p.m., then after frantic protests, a second voice vote was taken as Trump opponents shouted repeatedly for a roll call vote. The convention chairman then said there were not enough signatures to force the roll call.
