Missouri Governor Jay Nixon called an August 5 special election to fill three vacant seats in the state House of Representatives. The announcement came after being confronted with a lawsuit seeking to compel him to call special elections for four legislative seats. He has yet to set an election date to fill the Senate vacancy.

On February 13 House Republican Mike Moon filed articles of impeachment against Nixon for the delay in filling all four vacancies – a delay he says has denied representation for almost 300,000 Missourians.
