Texas Agriculture Commissioner Sid Miller won't face criminal charges for allegedly using taxpayer funds to obtain a "Jesus shot" in Oklahoma.

The Texas Department of Public Safety investigated the Republican for possible abuse of power. In a memo released Tuesday, prosecutors said they had determined "criminal intent would be difficult to prove."

The Houston Chronicle reported in March that Miller used taxpayer money to travel to Oklahoma last year to apparently receive a "Jesus shot," an anti-inflammatory injection meant to reduce chronic pain.

Miller reimbursed the state more than $1,000. He declined to say whether he got the injection.

The memo says Miller returned an additional nearly $500 since. It also says he calls the cost of the trips "relatively small" and says Texas has been refunded "all the money."
