Obama,Donald Young,and Larry Sinclair:Is there a Connection?

The Obama campaign is silent on whether Barack Obama has ever met a certain individual named Larry Sinclair.Anyway,did Donald Young choir director of the Trinity Baptist Church introduce Larry Sinclair to Barack Obama? Might this hurt Obama's family image if there is a connection between Young,Sinclair,and Obama? We believe Donald Young's murder has yet to be solved.Interesting questions.
