On 12 May 1999, Khizhnyakov became the Plenipotentiary Representative of the President of Russia [ru] to the Federation Council.[4]
The press has repeatedly accused Khizhnyakov of maintaining ties with the entrepreneur and head of the Olimp [ru] criminal group Yevgeny Kudryavtsev. Khizhnyakov was removed from the post as Plenipotentiary Representative in the Federation Council on 5 April 2004, after a commission of the Ministry of Internal Affairs conducted an investigation in Volgodonsk into mass extortion from entrepreneurs by members of Olimp. He was appointed assistant to the Plenipotentiary Representative in the Central Federal District instead.[5]
