Why do we suddenly develop foreign accents when saying foreign names?

Ever since President Obama appointed Sonia Sotomayor to take over the vacant seat that was left by retiring supreme court justice David Souter, I've been noticing something odd. It appears that news casters are suddenly developing Spanish accents when pronouncing Sotomayors last name. Granted, it is a name, and you do want to make sure it is pronounced correctly. So I can give the media a pass on this, but it did make me think of how people will spontaneously break into a foreign accent when talking.
