According to the Wrestling Observer newsletter, King Booker was against his recent transfer from the SmackDown brand to the RAW brand via the WWE draft. It was only a week before when King Booker was told that he was bring traded to RAW.
More politics are on RAW and with Triple H also on the brand, there is a huge Triple H influence. The last run which King Booker had on RAW only got him to mid-card status, as on SmackDown, he achieved the world title.
