Donald Trump’s favorite excuse? It was just a ‘retweet’

Donald Trump has repeated inaccurate and racially charged crime statistics, reposted pledges of support from white supremacists and retweeted dubious questions about the citizenship of his presidential rivals. It's all going out to an online following of more than 6 million people on Twitter alone.

His response when challenged? To dismiss it as nothing more than harmless "retweets."

Unlike presidential candidates before him, Trump has fueled his campaign for the Republican nomination with a seemingly endless series of eyebrow-raising statements. It's a strategy unavailable to a conventional politician but seemingly tailor-made for the master marketer.

Says, GOP consultant Kevin Madden: "Right when you think Trump is about to endure a concentrated level of scrutiny for a false statement or the latest outrage, he is on to the next controversy."
