Eli Stokols, national political reporter for POLITICO, and Reid Epstein, Wall Street Journal political reporter, preview the Republican National Convention in Cleveland.

Epstein said anti-Trump groups in the rules committee; including "Free the Delegates," "Delegates Unbound" and "Save Our Party;" led by Kendal Unruh, a rules committee member from Colorado, were trying to get 28 members to agree to alternative convention rules that could help upend Trump's nomination by formally "unbinding" delegates from the results of the primaries and caucuses, and delegates would instead be allowed to "vote their conscience."
