Donald Trump formally nominated as the Republican presidential nominee

Republicans formally nominated Donald Trump for president of the United States on Tuesday.

Trump has been the presumptive nominee since Sen. Ted Cruz exited the race following the Indiana primary in April, making Trump the last candidate standing.

Though Trump virtually clinched the nomination months ago, some Republicans delegates at this week's convention were still eager to voice their concerns with his nomination.

Some delegates opposed to Trump tried unsuccessfully to stage a roll-call vote on a measure that would have unbound delegates, a last ditch effort to permit them to vote against Trump. The chairman rejected the call for a vote after support for the roll-call vote collapsed.
