Though to be fair, it is an error that probably only one person in the entire world is likely to have noticed. (Rather, that person's wife, from the computer in the other room just now.)* It comes in this story about Obama's chief speechwriter Jon Favreau, and it is hidden somewhere in this paragraph:
During the campaign, the buzz-cut 27-year-old at the corner table helped write and edit some of the most memorable speeches of any recent presidential candidate. When Obama moves to the White House next month, Favreau will join his staff as the youngest person ever to be selected as chief speechwriter. He helps shape almost every word Obama says, yet the two men have formed a concert so harmonized that Favreau's own voice disappears.
Easily fixed! If the story were merely tweaked to say "the youngest person ever to be selected as a chief speechwriter for someone renowned for giving great speeches," fact-checkers would be content. Not that I'm counting, but Favreau is roughly two months more grizzled than the person who did that job under Jimmy Carter was at the time. Personally, I think the extra maturity will be a plus.
* I was emboldened to post this by an email from someone else who noticed. The message's subject line was, "Have you given up the mantle?" No indeed! Until some 26-year old shows up, or someone younger than my 27-years-and-4+-months at the start of the Jimmy Carter era, I'm clinging to the title!
