"Pete Souza, the former chief White House photographer credited with taking the photograph, confirmed on Threads that he took it on May 2, 2011, at 10:41 a.m. Eastern Time.
The Washington Post said it obtained the image by requesting all official White House photographs for the day bin Laden was killed. The Obama Presidential Library responded with a 161-page PDF document of all the images taken between May 1 and May 3, 2011. The photograph of Obama laughing at a printout of the meme can be seen on page 96, under the file name M1X152_7F42_9."
