I'm with John Gruber, who is hardly a fan of this administration:

"Calibri does convey a sense of casualness — and more so, modernity — that is not appropriate for the U.S. State Department. And I do not buy the argument that Calibri is somehow more accessible for those with low vision or reading disabilities. People with actual accessibility needs should be catered to, but they need more than a sans serif typeface, and their needs should not primarily motivate the choice for the default typeface."

Official departmental paperwork shouldn't look clownish.
