 The Iran scheme appears to be unrelated to Saturday's shooting targeting Donald Trump at a Pennsylvania rally. House Republicans are demanding answers from the Secret Service following Saturday's assassination attempt. Majority Leader Steve Scalise says the Oversight Committee will hold a hearing next week with Secret Service Director Kimberly Cheadle expected to testify. We're going to have a hearing Monday, and we're going to have some serious questions that she's going to have to answer, and I'm real concerned about her competence.
