Rep. Joe Wilson's outburst last week is drawing new recriminations from his colleagues, with a member of the Congressional Black Caucus suggesting that a failure to rebuke the South Carolina Republican is tantamount to supporting the most blatant form of organized racism in American history.

In an obvious reference to the Ku Klux Klan, Rep. Hank Johnson, D-Ga., said Tuesday that people will be putting on "white hoods and white uniforms again and riding through the countryside" if emerging racist attitudes, which he says were subtly supported by Wilson, are not rebuked. He said Wilson must be disciplined as an example.

The charged comments come as the House is preparing to take further action against Wiilson. House Democratic leaders decided to formally discipline him Tuesday afternoon for jeering President Obama during last week's joint session of Congress.

Wilson bellowed "You lie!" as Obama delivered his address.
