Investigative reporters from Chicago's Sun Times continue to examine the record of former Illinois State Senator Barack Obama. A new story emerged there yesterday.

A $100,000 state grant for a botanic garden in Englewood that then-state Sen. Barack Obama awarded in 2001 to a group headed by a onetime campaign volunteer is now under investigation by the Illinois attorney general amid new questions, prompted by Chicago Sun-Times reports, about whether the money might have been misspent.

The garden was never built. And now state records obtained by the Sun-Times show $65,000 of the grant money went to the wife of Kenny B. Smith, the Obama 2000 congressional campaign volunteer who heads the Chicago Better Housing Association, which was in charge of the project for the blighted South Side neighborhood.

Smith wrote another $20,000 in grant-related checks to K.D. Contractors, a construction company that his wife, Karen D. Smith, created five months after work on the garden was supposed to have begun, records show. K.D. is no longer in business.

The relationship between Smith and Obama dates to at least 1997, when Obama wrote a letter that Smith used to help the housing association win city funding for an affordable-housing development near the garden site. Plans called for more than 50 homes; a dozen ultimately were built.

Smith also has donated $550 to Obama campaign funds.
