AT&T has a long history of giving to political campaigns. Since the Center for Responsive Politics started tracking contributions in 1990, the telecommunications company has donated about $48.5 million, mostly to the Republican Party and its candidates.

CEO Randall Stephenson was a little light on political donations in 2011, but this year he's stepping up his game. In February alone, Stephenson donated $30,800 to the Republican National Committee, more than twice the amount of his total political contributions in 2011.
