FILE - In this Tuesday, April 1, 2014, file photo, Boston Red Sox designated hitter David "Big Papi" Ortiz takes a selfie with President Barack Obama, holding a Boston Red Sox jersey presented to him, during a ceremony on the South Lawn of the White House in Washington, where the president honored the 2013 World Series baseball champion Boston Red Sox. Ortiz tweeted the selfie to his followers Tuesday, and it was resent by tens of thousands, including Samsung, which retweeted it as an ad. The White House press secretary says Obama was not aware that the photo was part of a marketing stunt. (AP Photo/Carolyn Kaster, File)
