Katie Couric's Notebook: The Ku Klux Klan

Hi, everyone.

As America remembers the historic march in Selma 42 years ago, there are concerns about another part of our country's racial history -- the Ku Klux Klan.

In a new report, the Anti-Defamation League says that the Klan is coming back. The ADL says it's found traces of the KKK in 19 states...with as many as five thousand members, who are fighting new issues like immigration and gay marriage.

Pulitzer Prize-winning author David J. Garrow isn't convinced. He notes that the Klan's gatherings have been small -- at some places, 20 people or less show up. And he says, so far, there's scant evidence of violent crimes linked to KKK members.

But history teaches us to be vigilant. We've been told again and again that those who forget the past are condemned to repeat it.

The Ku Klux Klan is one ugly chapter from our past that we should never forget -- or repeat.

That's a page from my notebook.
