Here is a data entry error which plagued Obama for 17 years, from 1991 to 2007. His literary agent thought he was born in Kenya.
“You’re undoubtedly aware of the brouhaha stirred up by Breitbart about the erroneous statement in a client list Acton & Dystel published in 1991 (for circulation within the publishing industry only) that Barack Obama was born in Kenya. This was nothing more than a fact checking error by me — an agency assistant at the time. There was never any information given to us by Obama in any of his correspondence or other communications suggesting in any way that he was born in Kenya and not Hawaii. I hope you can communicate to your readers that this was a simple mistake and nothing more.”
The only problem is that she made the same error in 1991 and 1992 and 1993 and 1994 and 1995 and 1996 and 1997 and 1998 and 1999 and 2000 and 2001 and 2002 and 2003 and 2004 and 2005 and 2006 and 2007 – and then she fixed it right when Obama announced his candidacy for President.
