More than 30,000 Chicago Public Schools teachers and support staff will go on strike Thursday, after the unions were unable to reach a deal with the district.

"We have not achieved what we need to bring justice and high quality schools to the children and teachers of Chicago," Chicago Teachers Union President Jesse Sharkey said Wednesday night. "We need to have the tools we need to do the job at our schools. We need pay and benefits that will give us dignity and respect. We are on strike until we can do better." In response to the strike, Chicago Mayor Lori Lightfoot said that at "every turn, we bent over backwards to meet the unions' needs."

About 300,000 students attend Chicago's public schools; Lightfoot canceled classes for Thursday, but said administrators will be at all schools in case kids need a safe place to go. Negotiations will start again on Thursday. Chicago has the United States' third-largest school district. Catherine Garcia

A federal judge says the tragic death of her son "cannot be in vain."

U.S. District Judge Esther Salas spoke on Monday about the "unfathomable pain" her family has been experiencing since her son, a 20-year-old student at Catholic University of America, was shot and killed at their home by a man who was reportedly wearing a FedEx uniform. Salas' husband is recovering after being shot multiple times.

Salas in the video describes speaking with her son while they were cleaning up from his birthday party when he went to answer the door and she "heard the sound of bullets" as he was shot by a "monster" carrying a FedEx package. The primary suspect in the shooting has been identified as Den Hollander, who described himself as an "anti-feminist" lawyer and was "apparently angry at Judge Salas for not moving quickly enough on a lawsuit he had brought challenging the constitutionality of the male-only draft," The New York Times reports.

"We are living every parent's worst nightmare, making preparations to bury our only child, Daniel," Salas says. "My family has experienced a pain that no one should ever have to endure, and I am here asking everyone to help me ensure that no one ever has to experience this kind of pain."

Salas, who says she believes she was targeted by the "madman" because of "my position as a federal judge," says judges are "forced to live in fear for our lives because personal information like our home addresses can easily be obtained by anyone seeking to do us or our families harm," calling for steps to be taken that would "safeguard" their privacy.

"My son's death cannot be in vain," Salas says. "...This is a matter of life and death, and we can't just sit back and wait for another tragedy to strike." Brendan Morrow

President Trump's new campaign manager Bill Stepien on Monday expressed concern about voters receiving their mail ballots as early as late September, echoing GOP strategists who believe Trump is operating on an accelerated timeline to regain momentum before Election Day on Nov. 3.

Stepien wants to counter the expected nationwide surge in mail-in voting by holding more debates, but that likely wouldn't fix another potential looming problem for his campaign that may be, in part, Trump's own doing. Per The Washington Post, Trump's repeated attacks on mail-in voting, which he argues will lead to mass voter fraud, is discouraging Republicans from utilizing the practice and could threaten party turnout. A Monmouth University poll taken in July found that 60 percent of Democrats would at least consider voting by mail, compared to just 28 percent of Republicans.

In any other year, that might not be such a big deal. Sure, weather and forgetfulness could always prevent someone from going to the polls on Election Day, Politico notes, but the threat of a coronavirus outbreak is looming over this year's election and could keep more people at home than usual, which is partly why Democrats are pushing for more mail-in voting.

Republican strategists are hoping Trump rolls back some of his criticism, or at least makes it more specific, going forward, so Republicans don't refuse to vote absentee if they need to. "It is a problem," one GOP strategist in North Carolina told the Post. "The president has oversimplified the issue to criticize the method of voting, rather than the way it's done."

Don't get your hopes up for a running mate announcement from presumptive Democratic nominee Joe Biden this week.

Although Biden last week said that he was "going to have a choice" for his vice president pick "in the first week in August," The Washington Post reports that his search has been "extended," and the campaign is "signaling that it will likely wait until the second week of August" to tap his running mate. ABC News similarly writes that "it's looking like" the announcement won't happen this week.

As the search continues, Biden is expected to interview "five or six finalists," but he seems to be "entering the final phase of the search without a clear favorite," the Post reports. Last week, Politico reported that Biden's "biggest concern is that there is nobody on his list with whom he has any previous deep relationship," with this report suggesting a dark horse could potentially emerge.

Meanwhile, Politico reports that although the buzz has recently centered around Sen. Kamala Harris (D-Calif.), Sen. Elizabeth Warren (D-Mass.), Rep. Karen Bass (D-Calif.), Sen. Tammy Duckworth (D-Ill.), and former National Security Adviser Susan Rice, one Biden aide claims that "11 women remain in the mix."

But as the knives come out for some of the leading contenders during Biden's extended search, Rep. James Clyburn (D-S.C.) told the Post the situation has become "messier than it should be," and ABC News observes that "with just two weeks left before his convention, the coming time crunch could fray party unity at a moment his campaign needs it most."

"Picture this Thanksgiving: turkey, football (maybe), tenser-than-usual interactions with relatives," media columnist Ben Smith writes at The New York Times. "And perhaps a new tradition: finding out who actually won the presidential election."

The COVID-19 pandemic is expected to prompt a surge in mail-in voting, at a time when the U.S. Postal Service is grappling with service-slowing cost-cutting measures handed down by the new postmaster general, Louis DeJoy, a major donor to President Trump. Key states like Pennsylvania may be counting those ballots for weeks after Election Day, and with Trump filling that time tweeting more "false allegations about fraud," Smith writes, "the last barriers between American democracy and a deep political crisis may be television news."

TV hosts, election analysts, network chiefs, and social media executives exude "blithe confidence" about their ability to handle an election that won't be decided for days or weeks, Smith writes, but there's "near panic among some of the people paying the closest attention."

"The nerds are freaking out," Brandon Finnigan, the founder of Decision Desk HQ, told the Times. "I don't think it's penetrated enough in the average viewer's mind that there's not going to be an election night. The usual razzmatazz of a panel sitting around discussing election results — that's dead."

Media companies can prepare their viewers and change how they report election results, "but what the moment calls for, most of all, is patience," Smith writes. "And good luck with that."

"Nobody I talked to had any real idea how cable talkers or Twitter take-mongers would fill hours, days, and, possibly, weeks of counting or how to apply a sober, careful lens to the wild allegations — rigged voting machines, mysterious buses of outsiders turning up at poll sites — that surface every election night, only to dissolve in the light of day," Smith said. But one war game of an election in which Joe Biden wins a big popular majority and tiny electoral college loss ended with the U.S. military casting the deciding vote. Read more at The New York Times.

John Hume, who won the Nobel Peace Prize for his work ending "The Troubles" in his native Northern Ireland, died on Monday after a short illness, The New York Times reports. He was 83. Hume, a moderate Roman Catholic politician, worked doggedly for peace, inspired by the late U.S. civil rights leader Rev. Dr. Martin Luther King Jr. Hume played a major role in peace talks that led to the 1998 Good Friday Agreement. Former Prime Minister Tony Blair called Hume a "political titan" who "refused to believe the future had to be the same as the past," the BBC reports. Hume's family said it seemed "particularly apt for these strange and fearful days to remember the phrase that gave hope to John and so many of us through dark times: We shall overcome." Harold Maass

House Speaker Nancy Pelosi (D-Calif.) and Treasury Secretary Steven Mnuchin doubled down on their clashing coronavirus relief packages ahead of fresh Monday talks. Pelosi repeated Democrats' calls to renew the $600 per week in extra jobless benefits that expired Friday, although she said the sum could be reduced as unemployment falls. Pelosi said Democrats were "unified" behind the $600 figure, but that Republicans are in "disarray." Senate Republicans have proposed lowering the figure to $200 per week.

Mnuchin said in an interview on ABC's This Week that Republicans had suggested a one-week extension of the $600 during negotiations, but ultimately payments "should be tied to some percentage of wages, the fact that we had a flat number was only an issue of an emergency." Harold Maass
