The Russian trip for three U-S Senators has been canceled because one of them is on a so-called “black list.”  Wisconsin Republican Senator Ron Johnson was going to join New York Senator Jeanne Shaheen and Wyoming Senator John Barrasso.  Shaheen is a New Hampshire Democrat who was on a black list of unwelcome visitors Russia created in response to U-S sanctions.  Johnson was quoted as saying the Russian rejection of her visa request is “counter-productive to improving relations between our nations.”
