Warren Buffett publicly discussed Too Big to Fail: How Wall Street and Washington Fought to Save the Financial System — and Themselves in recent weeks on both Charlie Rose and CNBC.

On Charlie Rose, Buffett said of Too Big to Fail, “It’s a very good book.”

Separately, on CNBC’s Town Hall event with Warren Buffett and Bill Gates at Columbia University, Buffett told the audience about Too Big to Fail in response to a question from the audience.

After Buffett first read Too Big to Fail, he sent Sorkin a super-sized telegram with the following inscription:

Andrew,

Congratulations! Your book will be bigger than this telegram!

Warren
