Here is the latest Iowa news from The Associated Press at 3:45 a.m. CST

BISMARCK, N.D. (AP) — Protesters fighting the Dakota Access pipeline are getting conflicting messages from the Standing Rock Sioux reservation. The tribal chairman tells demonstrators that it’s time to leave their camp and go home. Another leader implores them to stay through the bitter North Dakota winter. The rival requests show how the camp’s purpose has widened beyond the original intent of protecting the tribe’s drinking water into a broader stand for Native American rights.

DES MOINES, Iowa (AP) — For six years as lieutenant governor, Kim Reynolds has traveled throughout Iowa alongside Gov. Terry Branstad, but rarely has she been in the spotlight. That’s about to change as Branstad has accepted an appointment as U.S. ambassador to China, giving Reynolds the opportunity to set priorities for the state. Those who have worked with Reynolds describe her as an enthusiastic and genuine person, but they’re not sure what to expect from her as governor.

IOWA CITY, Iowa (AP) — Peter Jok scored 23 points and Iowa upset 25-ranked Iowa State 78-64 on Thursday, snapping a three-game losing streak against its instate rival. Isaiah Moss had 14 points to help the Hawkeyes (5-5) to their first victory over a Power Five opponent this season.

CEDAR RAPIDS, Iowa (AP) — Police video shows an unarmed black driver struggling with an Iowa officer and a police dog before the officer shoots the motorist, paralyzing him. Driver Jerime Mitchell manages to get back inside his truck, with Cedar Rapids officer Lucas Jones clinging to him and then shooting him after the truck starts to roll. The dashcam video released Thursday seems unlikely to resolve a debate over whether Jones acted appropriately in the Nov. 1 shooting.
