A campaign official for the Barack Obama campaign says Michelle Obama will be in Kansas City and St. Louis Mar. 5.

She'll be at a Kansas City location in the morning, at a location to be determined, then head to St. Louis, the official said. (An earlier reference to a specific site may have been premature, the campaign says.)

Tickets in KC start at $200 each. The money will go to the Obama Victory Fund, a joint operation of the Democratic National Committee and Obama for America.

More as we get it.
