A handful of Senate Republicans have come out saying they may block John Bolton from being confirmed as deputy secretary of state, if Trump picks him. Kentucky Republican Senator Rand Paul says he would block John Bolton’s potential confirmation, saying, “There is something to be said for one of the top diplomats in the country being diplomatic.” Bolton was the former U.S. ambassador to the United Nations under George W. Bush. Bolton once famously talked about lopping off the top 10 stories of the United Nations headquarters. Trump’s pick for secretary of state, ExxonMobil CEO Rex Tillerson, has also sparked concern and pushback from both Senate Democrats and Republicans, many of whom are concerned about Tillerson’s close ties to Russia.
