A local congressman is the target of protests by some Native Americans... And his election opponent.
They want to know why Republican Steve King voted against a law to help prosecute non-natives who commit crimes on tribal land... Especially rape.
Friday protestors wrote a letter demanding answers from king, but he had little to say Friday evening.
The protesters gathered at the local Democratic headquarters, and marching with them was King's Democratic opponent Matt Campbell.
They were protesting king's vote against a law that makes it easier for tribal law enforcement to deal with non-natives accused of crimes on tribal land.
One study shows one in three Native American women will be raped in their lifetime.
"This is a very big issue. There are many untold stories out there. There are many women, there are many people in general, many Native American people that have been able to tell their story," said Deena Baker, a Native American.
"Mr. King has put us in harm's way. As women, we are very much in distress, and feel very unsafe at this time in Fifth District under the leadership of Mr. Steve King," said Native American Susan Barta.
King was not in his Sioux City office, but some of the protesters were invited inside.
"I got a little memo on that," said King.
But tonight at a political rally, King spoke out.
"They've never contacted me about this issue. This is completely a campaign stunt, and it should be viewed as that," said King.
King would not answer why he voted against the legislation.
"They don't even know what law they're talking about," said King.
King would not give an answer why he voted against the law, but many of the Native American women felt like he was not looking out for their well being.
