The Sun is welcoming back an old friend to its opinion pages: cartoonist Kevin “KAL” Kallaugher.  He’ll bring his sharp wit and inimitable style to a weekly take on the news in Maryland and beyond. Next Sunday, he’ll begin with a  KAL’s-eye view of the State House. In the meantime, enjoy an archive of some of his previous work for The Sun and a video in which the artist describes his exploits of the last six years as a globe-trotting cartoonist.
