Bruce Jenner has been flooded with messages of support since his emotional interview with Diane Sawyer on Friday. The general consensus is that the former Olympian's extended family is backing his decision to live as a woman. A tweet from Jenner's oldest son, however, casts some doubt on whether that support is actually genuine. On Saturday, Burt Jenner tweeted this cryptic note. "Having a hard time not putting a few people on blast who were not supporters before hand, but want to act like they were all along." The tweet has since vanished from the 36-year-old's Twitter page, but has succeeded in drumming up suspicion. Burt and his siblings Casey, Brandon, and Brody appeared in the Sawyer interview, in which Bruce revealed that Kim Kardashian had also been especially supportive. There is some question as to whether ex-wife Kris Jenner — who claims she was not asked to participate in the interview, something ABC News denies — is as comfortable with Bruce's transition as she says. Undoubtedly, it's a complicated and emotional situation. Perhaps now that Jenner's news is public, those close to him can begin to reconcile any doubts and truly show their support.
