DP William Ruto lacked 'necessary' papers, says Kibicho POLITICS Interior Principal Secretary Karanja Kibicho. [Edward Kiplimo, Standard] Deputy President William Ruto lacked the necessary travel documents to make the Uganda trip on Monday, Interior Principal Secretary Karanja Kibicho has said. In an interview with The Standard, Kibicho said that would be the only thing that would block the Deputy President from travelling abroad. However, the Interior PS did not reveal the specific document that Ruto lacked, saying the DP was best placed to issue the clarification. In an interview on Inooro FM yesterday morning, Ruto claimed that he was blocked from travelling ostensibly because he lacked clearance for the trip.
