The ad will run nationally on cable networks the group believes delegates will be watching

Washington (CNN) A group of Republicans pushing for delegates to be able to vote for and nominate someone other than Donald Trump at the convention this July is going up with a television ad nationally this weekend, the first such foray into TV.

The ad from Delegates Unbound, shared first with CNN, splices together clips of Republican icon President Ronald Reagan and Donald Trump. In one such juxtaposition, Reagan says, "Use of force is always and only a last resort," while Trump says "I would bomb the s--- out of them," a statement he made referring to ISIS.

The ad closes with text: "GOP delegates: Follow your conscience" with a link to Delegates Unbound's website.

CNN has reached out to the Trump campaign for comment.
