Trump demonstrates how easily persuadable he is by responding via Twitter to “Fox & Friends” almost every day. His campaign and White House staffers have admitted to this several times, albeit not on the record. But their actions have made clear they believe this: White House chief of staff John Kelly has reportedly prohibited staff members from giving Trump reading materials. More recently, Democratic Senate leader Chuck Schumer asked that presidential aide and immigration hard-liner Stephen Miller be kept out of an immigration meeting, lest he shape the president’s thinking too much. Even Russian-controlled Twitter accounts have apparently been set to tweet at Trump during times he’s habitually online.
