Sam is charged with extortion. It is alleged that he demanded protection money from store owners. One of the store owners, Josh, is willing to testify about how Sam demanded money from him. Two days before trial, Josh changes his mind and refuses to testify. He says that he received a letter from Sam, in which Sam threatens to harm his family if he would testify. The prosecution offers a police officer to testify about what Josh told him about Sam's extortion. Sam objects.

Sam objects on the constitutional ground. He claims that to allow the police officer to testify would violate his right of confrontation as guaranteed by the Sixth Amendment to the Constitution. The court should ____________ Sam's claim.
