Republican candidate for Missouri governor Eric Greitens has outraised Democratic opponent Attorney General Chris Koster in recent weeks, but Koster still has more cash to spend.

Reports provided to The Associated Press on Thursday in advance of campaign finance filings show former Navy SEAL officer Greitens raised about $4.6 million from July 21 through Aug. 27.

Koster raised about $2 million in cash. He received in-kind contributions of more than $1 million.

But Koster has nearly three times the amount of cash as Greitens, with close to $9.5 million compared with Greitens' $3.2 million.

Greitens spent millions of dollars on a contentious four-way GOP primary Aug. 2. He's spent more than $10 million on his gubernatorial bid.

Koster faced a less costly Democratic primary. He's increased spending since then.
