(CNN) This is the story of a little PO box in Northern Virginia and the conspiracy that wasn't. When the Republican presidential primary was still in full swing in March, officials from Donald Trump's campaign promoted a conspiracy theory -- one of many -- insisting there was a nefarious link between his political opponents and an anti-Trump super PAC. It began this spring when a group called Make America Awesome, an anti-Trump group, posted a photo of Trump's wife, Melania, that criticized her for posing semi-nude in a magazine photo shoot. Trump responded by crudely lambasting the physical appearance of Ted Cruz's wife, Heidi, and he justified it by claiming that Cruz was behind the attack on his own wife.Why do many campaigns and Super PACs share the same PO box?The reason is a lot less interesting than the conspiracy that has been alleged 
 Question:Because those groups listed the same address, they claimed it was proof that the anti-_ forces were operating from the same source.

Ex Output:
Donald Trump
