For instance, here's one from the White House Press Secretary's Office, as reported by POLITICO:
In a White House press release sent Tuesday evening, there's a misspelling, and it's a big one: The first lady's first name.
"Michele and I are deeply saddened by the loss of life, injuries, and damage that have occurred as a result of the recent earthquake and tsunami in West Sumatra," reads the release.
Of course, the first lady's first name is spelled "Michelle," with two "l"'s.
A corrected version was sent out this morning.
