>> reporter: now the cohen camp is responding by mocking giuliani. a source close to michael cohen said this to jake tapper. you think he is wild speculation as if he were unhinged? obviously, it's a lie. shocking. he is touting academic growth and campaigns to extensively for republicans this fall. as the president heads back to the white house tonight he has to confront questions about cohen when he meads side-by-side with the italian prime minister tomorrow night at the white house and maybe see him address the controversy before then but so far trump has been uncharacteristically quiet on social media as well this week. >> he has been extremely quiet. thank you, sarah westwood. joey jackson is with us and julian zeleny now.
