Chad Kroeger performs with Nickelback at the MuchMusic Video Awards in Toronto on Sunday June 21, 2009. Twitter and YouTube's decision to delete an edited clip of Nickelback posted in a political attack by Donald Trump came down to copyright complaints, but lawyers say the actions of the U.S. president may run afoul of other laws that protect singer Chad Kroeger's likeness from being used without his permission. It's a situation that's coming up more frequently as meme culture, once dismissed as a teenage phenomenon, becomes part of the daily conversation. THE CANADIAN PRESS/Nathan Denette
