Obama praises Chattanooga as 'a tornado of innovation'

President Barack Obama speaks at Cedar Falls Utilities on Wednesday, Jan. 14, 2015, in Cedar Falls, Iowa.

President Obama lifted up Chattanooga for a second consecutive day as an example of what high-speed Internet service can bring to a community, calling the Scenic City "a tornado of innovation."

In a speech today in Cedar Falls, Iowa - another city with gigabit-per-second Internet speed through its municipal utility - Obama praised the turnaround in Chattanooga.

Obama said as "an old railroad town" Chattanooga was once the dirtiest city in the nation and suffered more than most during the recession.
