Attorney General Marty Jackley says he is investigating the nominating petitions of candidates for South Dakota's open U.S. Senate seat.
The announcement came Tuesday - a day after Sioux Falls state Representative Steve Hickey accused candidate Annette Bosworth of violating election law.
South Dakota Attorney General Marty Jackley isn't naming names at this point but says more than one candidate is being investigated.
He may be looking at Bosworth, who has been the subject of two challenges to her nominating petitions and was called out by Hickey on Monday.
"I am glad for his response today and we will just sit patiently and expect his decisions," Hickey said.
In a news release Monday, Hickey said allegations of election law violations in the Bosworth camp have been turned over to the Division of Criminal Investigation.
Hickey received the information after he tried to challenge the petitions in court himself in April. Hickey believes Bosworth signed her name as a petition circulator during a time frame when she was in the Philippines on a mission trip.
"We've got a bunch of signatures where she is literally not the signature collector and she signed and notarized she is, and we know that's a serious violation," Hickey said.
Hickey withdrew his challenge after he was told it would not result in Bosworth's name being removed from the ballot.
KELOLAND News tried to call and text Bosworth on her cell phone Tuesday but received no response. Her attorney also did not return a phone message.
Hickey says he's challenging Bosworth because he wants a fair election.
"I want the process to have integrity. I want the GOP, I want everyone to know we'll clean our own house too, that's important and so that's going to happen," Hickey said.
Jackley tells KELOLAND News that Secretary of State Jason Gant turned over concerns about the candidates' petitions because the issues that have been raised are outside of his authority.
Gant has certified all the names of the U.S. Senate candidates and they will all appear on the ballot no matter the outcome of the investigations.
