10:48 p.m. – Some protesters continue to stay on I-94

There are still demonstrators on I-94, 3-plus hours after the St. Paul march on the highway started.

Police said they were giving people still there the chance to exit the freeway, but noted "aggressors" were still throwing, rocks, bottles and rebar from a construction area at officers.

Police have also been using marker rounds.

There are dozens of people still on the road, mostly peaceful.

But the protesters haven't budged.

Photos on Twitter show buses arriving on scene. Some people in the crowd write that they're putting on goggles and masks in case tear gas is used – note, the police have not confirmed whether or not that is actually going to happen.
