The fifth State Dinner was held on October 13, 2011 for South Korean President Lee Myung-bak at a cost of $203,053.34, the CBS report said.
It said the State Department has not yet responded to another Freedom of Information request filed seven months ago for its rundown of the expenses for the sixth State Dinner honoring British Prime Minister David Cameron on March 14, 2012.
Obama hosted French President Francois Hollande during his seventh State Dinner last night.
The US Congress has been waiting for similar information from the State Department even longer, it said.
In a letter to then-Secretary of State Hillary Clinton dated November 1, 2012, Darrell Issa, a Republican lawmaker from California, Chairman of the House Committee on Oversight and Government Reform, had expressed concern about the costs of state dinners and asked for an accounting.
"Please provide," wrote Issa, "an itemised list of costs and expenses for each of the last six state dinners, including, but not limited to, amounts paid, including reimbursements, for non-government event planners, entertainers and chefs."
Issa gave Clinton two weeks, until November 15, 2012, to respond to his request. The CBS, quoting a staffer says the Committee never received a response from Clinton or the State Department, the report said.
