Good morning! Here are top Minnesota and national headlines to start your Tuesday with:

We get a weather reminder today that spring has started in Minnesota. Most parts of the state will see highs in the 40s in the afternoon, with clear, sunny skies. Get the latest from Updraft.

Downtown Minneapolis has been transformed into something reminiscent of Cold War-era Berlin before Derek Chauvin's trial starts. 

Racial justice activists say the city is sending a wrong message that makes "it seem like the protesters are the problem, not the police violence that led to our protests." During the trial, currently set to begin next Monday, as many as 1,100 police and several thousand National Guard members will patrol Twin Cities streets that were filled with demonstrators last summer following the police killing of George Floyd.

A court decision that could delay the Chauvin trial is still pending with less than a week left until Day One of the trial. 

Judges who heard arguments on whether to reinstate a third-degree murder charge against Chuavin said after the hearing that they would expedite the process and release their decision as soon as possible. If the charge is reinstated against Chauvin, it’s likely that attorneys will be given more time to prepare their cases — putting next week’s start of the trial in jeopardy.

This week, Minnesota expects to get more than 45,000 J&J one-shot doses.

The COVID-19 vaccine, approved for emergency use over the weekend, is being shipped to and arriving in states across the U.S. this week. The company said on Monday that nearly 4 million doses had been shipped in the nation and "within about the next 24 to 48 hours, Americans should start receiving shots in arms."

36,000-plus Minnesotans are getting vaccinated daily -- the highest level since the state's efforts kicked off in December.

The latest Health Department data shows state inoculations on an upswing with roughly 159,000 shots reported the past three days. The seven-day rolling average is running at more than 36,000 a day currently. And that number might rise furthermore with the J&J vaccine arriving in the state soon.  

Here are Minnesota’s latest COVID-19 statistics: 

• 6,486 deaths (3 new)
• 485,230 positive cases (636 new); 97 percent off isolation
• 16.2 percent of Minnesotans 16 and older with at least 1 dose
• 52.6 percent 65 and older with at least 1 dose

Gov. Tim Walz wants districts to offer in-person learning to all Minnesota middle and high schoolers by next Monday. Some schools say: “I don’t think we can do that.”  

We're now less than a week away from the March 8 deadline Walz set for returning middle and high school students to the classroom. Many districts have met or will be able to meet the goal, but for Minnesota's largest districts, all in the metro area, it'll still be a work in progress. According to the districts' plans for secondary schools, many students won’t transition to new in-person schedules until after spring break.
