Five Idaho State Police troopers are heading to Arizona for 21 days to help with border security, Gov. Brad Little said Thursday. 

The Republican governor said the troopers will start a 21-day mission on Tuesday to help Arizona law enforcement officials with intelligence gathering and investigative work to prevent illicit drugs from crossing the border.

Republican Govs. Doug Ducey of Arizona and Greg Abbott of Texas sent a letter to fellow governors last month asking for law-enforcement help.

Little said it will cost Idaho just over $53,000 to send the troopers to Arizona

Four other states with Republican governors are also responding. Florida, South Dakota, Iowa and Nebraska are sending troopers or National Guardsmen to  Arizona and Texas.

In Arizona, the Idaho troopers will be deputized and will act under the same authority given to Arizona State Troopers.
