A leader of conservatives making a last-ditch attempt to block Donald Trump's nomination says she's dropping her effort to force the US Republican National Convention to vote on her plan to let delegates back any presidential candidate they want.
The convention rules committee has already rejected Colorado delegate Kendal Unruh's proposal to "unbind" delegates from the candidates they were committed to by state primaries and caucuses.
Unruh had been saying that despite that defeat, she'd get enough support to force a full convention vote next week on her plan to let delegates vote their conscience.
But she said on Friday that the Trump campaign and party officials have peeled away that support.
She says she and her supporters believe delegates already have the right to vote their conscience and will oppose Trump's nomination.
