WATCH: Stephen Bloom defends Iowa comments on NBC's 'Rock Center'

Atlantic piece drew criticism from many corners

When Stephen Bloom, a journalism professor at the University of Iowa, published 'Observations From 20 Years of Iowa Life' on The Atlantic's website in early December, he might never have imagined the controversy his story would create.  Bloom's article went viral during the weeks leading up to the Iowa caucuses, eliciting thousands of comments, a critique by the University of Iowa's president, and even threats against the professor. NBC's Willie Geist met with Stephen Bloom recently to talk about the controversy and see if Bloom's message about Iowa has changed.
