Members of Congress are afraid to go after Obama because of a combination of these two factors: 1. The media would label them as racist since Obama looks black. 2. Congress is complicit in the biggest hoax/fraud (Obama presidential usurpation) in US history. If Congress goes after Obama, the truth emerges and many of them go straight to prison for treason. Racism fear is a significant factor, but the main reason they will not act is that Members of Congress are protecting Obama to protect themselves. It is that simple.
