The number of in-person voters in Maricopa County taking part in the state’s Democratic presidential preference primary today has surpassed the number who took part at the county level for the 2016 Democratic presidential preference primary, Maricopa County Elections Department spokeswoman Megan Gilbertson told NBC News.

Maricopa County accounts for more than half of the state’s registered Democratic voters. This is especially notable because the Democratic race was more competitive in and the high Democratic turnout took place despite coronavirus concerns and despite the county closing one-third of its polling locations over the weekend.

The Philadelphia Police Department said Tuesday that, because of coronavirus, certain non-violent offenders will be arrested at a later date pursuant to an arrest warrant. 

The measure means that a person will be detained, officers will complete the appropriate paperwork, confirm the offender’s identity and then let them go. Later, they will arrest the person and they will be processed and prosecuted per normal procedure.  

There is an exception, the Police Department says, “if a police officer believes that releasing an individual would pose a threat to public safety, the officer will notify a supervisor, who will review the totality of the circumstances, and in the interest of public safety, utilize discretion in determining the appropriate course of action.”

The move comes amid growing concern over how the coronavirus could wreak havoc in U.S. jails.

Kansas public school children will be out of class for the remainder of the 2019-2020 school year, the governor announced Tuesday in an effort to combat the spread of the coronavirus illness COVID-19.

“This was not an easy decision to make,” Gov. Laura Kelly said in a statement.

While Kansas appears to be the first state to cancel the remainder of the academic year, California Gov. Gavin Newsom on Tuesday said it was unlikely that schools will re-open this spring. 

Kansas has 16 confirmed cases of COVID-19 as of Tuesday afternoon, according to the state’s health department. One death linked to the illness was reported by the governor on March 12.

San Francisco announced late Tuesday that marijuana dispensaries may stay open during the city's shelter-in-place order, reversing an earlier decision that drew complaints from stores and their customers.

City health officials had earlier put a halt to pot shop sales under emergency measures related to the coronavirus pandemic, the San Francisco Chronicle reported. 

Sen. Bernie Sanders, I-Vt., on Tuesday outlined his coronavirus proposals in a speech from his campaign headquarters in Washington, D.C. — items that include sending households $2,000 a month for the duration of the crisis.

Sanders opened his address by saying the country was "facing an unprecedented series of crises" that he believes will require a $2 trillion stimulus to avoid "economic catastrophe."

His lengthy list of proposals included government covering all coronavirus-related medical bills, speed up testing, invoke emergency powers to scale up production of supplies like surgical masks and ventilators, and provide substantial unemployment insurance to those who lose jobs as a result of the outbreak.

Sanders enters Tuesday's primaries trailing frontrunner Joe Biden in the NBC News projected delegate count.

After weeks of downplaying the risks posed by the coronavirus outbreak and lashing out at his critics, President Trump has since embraced a more urgent approach and sober tone as he’s implored Americans to do their part to help stem the spread.

From insisting a week ago that the virus will “go away” if Americans “just stay calm,” the president now admits the pandemic is “not under control.”

His previous statements also contradict his assertion Tuesday that he “felt that it was a pandemic long before it was called a pandemic.”
