Black Hawk County Sheriff Tony Thompson said he is done with "the enormous failure" of Test Iowa.

"The realities of Test Iowa appears to be a $26 million publicity stunt for the Governor and nothing more,” Thompson told KCRG-TV9.

The comments came as the Governor's Office reversed course on its plan to close the Test Iowa site in Waterloo and move it to Marshall County, which already had higher test rates and fewer cases than Black Hawk County. On Friday, the state changed its mind and decided to keep the Waterloo site open through May 28th.

The initial decision to close the Test Iowa site drew frustration from Sheriff Thompson at a news conference Thursday.
