"What an honor to be in the nation's capital for America's biggest birthday party," Bergeron said in a statement Monday. "Hosting 'A Capitol Fourth' enables me to celebrate two things I'm a big fan of -- America and PBS."
"We are thrilled that Tom Bergeron will lead our nation in this star-spangled celebration," said executive producer Jerry Colbert. "We are also humbled that the viewers have chosen this unique live television event as their favorite. With the eyes of America upon us, we join as one family to celebrate our freedoms, using the magical medium of television."
