Roger Stone is encouraging Donald Trump supporters to descend upon Cleveland in the event of a contested convention, saying that they'll have the opportunity to confront outed delegates trying to "steal" the GOP nomination from the New York businessman.

"We're going to have protests, demonstrations -- we will disclose the hotels and the room numbers of those delegates who are directly involved in the steal," Stone told the Freedomain Radio podcast. "If you're from Pennsylvania, we'll tell you who the culprits are. We urge you to visit their hotel and find them."

Here's more from Stone:

The fix is in. If Trump does not run the table on the rest of the primaries and the caucuses, we're looking at a very, very narrow path in which the kingmakers go all out to cheat, to steal, and to snatch this nomination from the candidate who is overwhelmingly selected by the voters, which is why I have urged Trump supporters: come to Cleveland. March on Cleveland. Join us in the Forest City. We're going to have protests, demonstrations -- we will disclose the hotels and the room numbers of those delegates who are directly involved in the steal. If you're from Pennsylvania, we'll tell you who the culprits are. We urge you to visit their hotel and find them. You have a right to discuss this if you voted in the Pennsylvania primary, for example, and your votes are being disallowed.

The key bit starts at around the 47-minute mark.
