Delegates loyal to Trump and the Republican National Committee fought back by proposing a counter-measure to clarify that all delegates are bound to vote based on the primary results.
It's still not technically over for the group: anti-Trump leaders will have until Monday to submit the names of 28 rules panel members who support the effort in order to force a vote on the floor of the full convention.
Ken Cuccinelli, former delegate manager of Texas Sen. "Well, you had your chance to do that on primary day in your state".
The effort failed even with the support of Lee, who also was in the meeting with Blackwell and Cuccinelli, as well as Unruh.
His efforts ran counter to the message by Republican leaders who, during a week of pre-convention meetings here, called for party unity and the need to coalesce behind Trump, who won a majority of convention delegates in primaries and caucuses. Delegates from open primary states like New Hampshire, South Carolina and MS argued against it.
"During the pause as we were trying to get all of this together, we were approached by a number of members... who asked if they could have a period of time who asked if they could work out their differences...." "They didn't want to do that".
"I think that we would love to have him, don't get me wrong", Spicer said.
Trump campaign chairman Paul Manafort declared the anti-Trump movement dead Thursday evening.
Some anti-Trump delegates still insist that they are free to vote how they choose under the current rules.
"What was fantastic was seeing those "Trump-RNC No" and "Trump-RNC Yes" signs".
Kendal Unruh, the Colorado delegate who authored the proposal, said afterward that she would try gathering the signatures of 28 rules committee members needed to force a convention floor showdown.
The Trump campaign did not immediately respond to questions about Tebow's departure from a convention program that the NY billionaire's team had long teased would be an extraordinary display of political entertainment.
"This just proves that Donald Trump did not have the support of enough delegates to be the nominee", Delegates Unbound co-founder Dane Waters said in a statement. "This act by the Rules Committee just highlights the hypocrisy of the RNC".
"I personally have received 440 emails to vote my conscience, to unbind..."
"The fight is far from over in Cleveland".
