The Sioux Falls City Clerk says Walmart is challenging petitions against building a new store in Sioux Falls.
Walmart officials say 2,084 signatures are deficient.
City Clerk Lorie Hogstad says an affidavit came at 4:25 p.m. on Monday; the company had until 5 p.m. to submit its challenge.
Now Hogstad says she will have to answer every deficiency in writing. She says verifying these claims could take weeks.
