(AP) -- JEFFERSON CITY, Mo. (AP) -- Republican Dave Spence has chipped in an additional $500,000 to his campaign for Missouri governor.
Online reports filed with the Missouri Ethics Commission show Spence made the contribution earlier this week and reported it Wednesday.
Spence also put money into his campaign earlier this month. The suburban St. Louis businessman has now plugged $5 million into his effort to unseat Democratic Gov. Jay Nixon.
Spence and Nixon have also been helped by funds from their parties' national governors' associations.
