Maria Shriver posts inspiring quote for MLK Day

Maria Shriver takes to Twitter to post about Martin Luther King Day on Jan. 16. She tweets, "On this #MLK Day, may we all learn from from a true architect of change and each ask more of ourselves as citizens to help move humanity forward."

She follows this up with an MLK quote."Darkness cannot drive out darkness; Only light can do that. Hate cannot drive out hate; Only love can do that."                                                                                                                                                       -Martin Luther King Junior
