On the Trail: June 5

President Obama's re-election campaign has filed a trademark infringement lawsuit against a website selling campaign paraphernalia featuring the signature "O" logo, with the "rising sun," and the 2010 logo that includes the letter "O." According to the lawsuit, "The campaign is being harmed by the sale of competing products. It also takes away money from the sale of campaign merchandise that could help fill the campaign's coffers. The owner of the Demstore.com site expressed disappointment and said, "We have always cooperatively worked with Democratic campaigns."
