When I did some fact checking on Seth’s tweet, Romney’s camp in late 2011 stated that he actually said “Keep America America,” instead of “Keep America American.” It is also reported in the article below that “Rev.” Al Sharpton (now a television host) labeled this as “innuendo.”  No further comment on either statement….
