OMAHA, Neb. (KMTV) -- Delegates approved a resolution aimed at stopping what Senator Ben Sasse wants: a third option for President.

On Saturday-- Sasse's own Republican Party in Nebraska took formal steps to stop his movement.

Voting to adopt a resolution opposing any elected Republican official's effort to draft a third party candidate- like Sasse has done.

Republicans greeted Senator Sasse was with a standing ovation early this morning, but were later in the day voting on whether or not he should be allowed to call for the party to "Dump Trump".

"There are political issues about which we have some disagreements in the room, I don't want to linger on any of those today, but I want to acknowledge that I know that they exist," Sasse said this morning while addressing the convention.

Resolution 8 reads, “The party will oppose any effort by an elected official to support a third party presidential candidate.” Ultimately, saying it helps Hillary Clinton.

"Any effort to support a third party candidate will have the effect of ensuring that the Republican Party and our nominee doesn't get elected in the fall," said David Kramer, a former Nebraska Republican Committee member.

Longtime Nebraska Republican Sam Fischer, nephew of Senator Deb Fischer, introduced the resolution.

Sen. Fischer’s office says it isn't behind the resolution.

"They'll hope that by the time the general election rolls around, he will have seen the best course of action for the future of our party and the future of our country is to support the Republican nominee for president," Kramer said.

Another resolution- being perceived as "anti-Trump" was also put to delegates: this one stating that "the Nebraska Republican Party will strongly oppose all degrading remarks towards women, minorities, and other elected officials, including candidates for the President of the United States."

This resolution was rejected.

Trump overwhelming won the Nebraska primary-- which was the first after other candidates dropped out.
