I study a Bayesian persuasion model in which multiple senders sequentially persuade one receiver, after observing signal structures of prior senders and their realizations. I develop a geometric method, recursive concavification, to characterize the Subgame Perfect Equilibrium paths. I show that if there are two senders who have constant-sum payoffs, the truth-telling signal structure is always supported in equilibrium. I prove the existence of the silent equilibrium, where at most one sender provides nontrivial information. I also provide a sufficient condition under which it is without loss of generality to focus on silent equilibria.
