Businessman Humphreys gives $500K to Greitens for governor

JEFFERSON CITY, Mo. (AP) -- Missouri gubernatorial candidate Eric Greitens is getting financial support from a wealthy businessman who had backed one of his rivals in the Republican primary.

State campaign finance records show Joplin businessman David Humphreys gave $500,000 to Greitens on Wednesday.

Humphreys gave $750,000 to Lt. Gov. Peter Kinder during the Republican gubernatorial primary, which Greitens won.

Humphreys is an executive at TAMKO Building Products and a supporter of so-called right-to-work laws, which bar workplace contracts in which union fees are required of employees.

Greitens and Kinder both support right-to-work laws.

Missouri's Republican-led Legislature passed a right-to-work bill last year, but it was vetoed by Democratic Gov. Jay Nixon.

Nixon is term-limited this year.

Greitens is running for governor against Democratic Attorney General Chris Koster.
