Joe Biden formally introduced Sen. Kamala Harris as his running mate on Wednesday, telling a socially-distanced gymnasium in Wilmington, Del.: "I have no doubt that I picked the right person to join me as the next vice president of the United States of America."

Why it matters: Harris is a historic pick for vice president, becoming the first Black woman and first South Asian woman to be named to a major-party U.S. presidential ticket. "Kamala knows how to govern," Biden said. "She knows how to make the hard calls. She is ready to do this job on day one."

Rep. Adam Kinzinger (R-Ill.) tweeted Wednesday that QAnon has "no place in Congress," a day after Marjorie Taylor Greene, a vocal QAnon conspiracy theorist, won the Republican nomination in a congressional runoff election in Georgia.

Why it matters: Few, if any, Republican members of Congress have publicly condemned the far-right conspiracy, which baselessly claims that a secret cabal of sex traffickers within the "deep state" is waging a war against President Trump.

Democrats and the Trump administration remain "miles apart" on negotiations over a coronavirus stimulus deal, House Speaker Nancy Pelosi (D-Calif.) said on Wednesday.

The latest: Around 3 p.m., Pelosi and Senate Minority Leader Chuck Schumer (D-N.Y.) issued a statement saying that Treasury Secretary Steven Mnuchin had initiated a phone call and made clear that the White House is "not budging from their position concerning the size and scope of a legislative package."

New Jersey Gov. Phil Murphy (D) announced Wednesday he will sign an executive order allowing private and public K-12 schools and universities to reopen for in-person learning in September.

The big picture: New York and New Jersey have now authorized school districts to begin reopening. Both states and Connecticut ordered travelers from 31 states to quarantine before crossing their state borders after they were able to manage the pandemic.

House Oversight Committee Chair Carolyn B. Maloney (D-N.Y.) introduced a bill to restrict changes to the U.S. Postal Service's level of operation, the representative's office announced on Wednesday.

Why it matters: The bill comes amid increased scrutiny from Democratic lawmakers, who say recent efforts to restructure USPS threaten the use of mail-in ballots for the November election. Maloney further notes that individuals depend on USPS for critical deliveries, including medications.

America's confidence in the public school system rose by 12 points this year to 41% — its highest point since 2004, according to a Gallup poll released Wednesday.

Why it matters: "Double-digit increases in confidence for any institution are exceedingly rare," Gallup notes. The jump comes as teachers, administrators and parents are still figuring out how to safely get kids back to school in the midst of a global pandemic, as the U.S. reports the most coronavirus infections and fatalities in the world.

Sen. Kamala Harris, tapped Tuesday as Joe Biden's running mate, is not a "break up Big Tech" crusader. But should Democrats win in November and seek to go after Silicon Valley, she could bring prosecutorial rigor to the case.

Why it matters: The vice president doesn't normally run a president's tech agenda, but can still help set the tone on a wide range of issues for a presidential campaign and administration. Harris' familiarity with the firms in her backyard may give her an outsize role on tech policy.

An order from President Trump that would ban TikTok in the U.S. is putting in jeopardy TikTok's plan to hire 10,000 U.S. employees, according to a source familiar with the company's thinking.

Why it matters: When TikTok first rolled out the job pledge, it served as a carrot in the political conflict over the social video service, but it's now being held out as a stick.

President Trump on Wednesday tweeted congratulations to Marjorie Taylor Greene, a vocal QAnon conspiracy theorist who won the Republican nomination in Georgia's deep-red 14th Congressional District runoff.

Why it matters: The president's approval illustrates how the once-fringe conspiracy theory has gained ground within the GOP. Greene is among the at least 11 GOP candidates for Congress who have openly supported or defended the QAnon movement or some of its tenets, per Axios' Jacob Knutson.

Sen. Kamala Harris' VP selection could heighten the ticket's focus on environmental justice while prompting fresh Trump campaign political attacks on Democrats' energy plans.

Why it matters: Her introduction comes in an election year that has seen more emphasis on climate change than prior cycles. One effect of the movement ignited by the police killing of George Floyd is a new focus on environmental burdens that poor people and communities of color face.

President Trump in a tweet Wednesday morning boasted about a policy meant to block low-income housing from suburbia and argued that former Vice President Joe Biden and Sen. Cory Booker (D-N.J.) would allow affordable housing to "invade" the space of the "suburban housewife."

Why it matters: The policy has drawn harsh criticism and been seen as a form of segregation. The Obama-era provision that was reversed by Trump's policy sought to fight against housing discrimination.

Major cities saw a spike in murders this summer, even as overall crime rates remained at a generational low, according to The New York Times.

Where it stands: The average murder rate across 20 major cities averaged 37% higher at the end of June than at the end of May, the Times reports, citing University of Missouri-St. Louis criminologist Richard Rosenfeld. It increased by 6% over the same period last year.

Joe Biden's initial list of possible contenders was roughly 20 governors, senators, congresswomen, mayors and other Democratic stalwarts — young and old; Black, Hispanic, white, Asian; straight and gay, AP reports.

How it works: Harris was among the party's most popular figures, a deft debater and a fundraising juggernaut.

What we're hearing about Joe Biden picking Sen. Kamala Harris as his running mate from the text chain of the Axios political team.

White House editor Margaret Talev: So far, Harris has been the hardest for Trump to brand. The initial Trump campaign response is to brand her as a sellout willing to look past her earlier concerns about Biden.

Three quick points about Joe Biden's historic selection of Sen. Kamala (pronounced COMMA-luh) Harris of California as his running mate — and clues they give us to how Biden would govern:

1. She was always at the top of his list. As I look back through my text threads with top Dems over the past five months, she was always assumed to be the most likely pick.

An "admitted leader of the Ku Klux Klan" has been sentenced to six years in prison for driving his vehicle into Black Lives Matter protesters in Richmond, Virginia, and faces more charges before a grand jury next month, per the Richmond Times-Dispatch.

The big picture: Harry H. Rogers, 36, of Virginia, received the maximum penalty for "six misdemeanors, including assault, destruction of property and hit-and-run charges" over the June 7 incident after a judge in Henrico County District Court convicted him on Monday, the New York Times notes. The judge ruled the attack was not a hate crime because "the victims were white," WTVR-TV reported. Rogers' three outstanding felony charges are for alleged attempted malicious wounding, AP reports.

More than $10.8 million was donated in four hours after Sen. Kamala Harris was announced as presumptive Democratic presidential nominee Joe Biden's running mate Tuesday, the Democrats' main donation-processing platform ActBlue said, per the New York Times.

Why it matters: Biden is lagging behind in fundraising to President Trump, whose campaign and the Republican National Committee out-raised that of the Democrats' last month. But Biden's announcement triggered his campaign's "best fund-raising hour," his deputy digital director, Clarke Humphrey tweeted, adding it was the campaign's "best grassroots fundraising day ever." ActBlue took $2.3 million in donations during the same hours of 4pm to 8pm Monday, "suggesting a bump as large as $8.5 million" for Biden, the Times notes.

President Trump said during an interview with conservative radio host Hugh Hewitt Tuesday he'd love to hold campaign rallies, but he "can't because of the covid. ... you can't have people sitting next to each other."

Why it matters: Trump is known for electrifying crowds at rallies and connecting with loyal supporters on a huge scale. But Trump stressed to Hewitt and in a separate radio interview earlier Tuesday that it wouldn't work while social distancing is required to prevent the spread of COVID-19. "You can’t have empty seats," Trump told with Fox News Radio.

Rep. Ilhan Omar (D-Minn.) won the Democratic primary against lawyer Antone Melton-Meaux on Tuesday evening, AP reports.

Why it matters: The race is one that's played out across the U.S. as progressives continue to sweep party nominations. Omar's win officially means all four progressive members of "The Squad" have won their primary elections.

Local police officers are seeking felony charges in 25 cases following the arrest of 100 people in the wake of widespread looting and property damage in Chicago on Monday, per the Washington Post.

Driving the news: Law enforcement said the event involving hundreds of people was a coordinated response after an officer shot a suspect Sunday evening, according to CBS Chicago.

Gun-rights activist Marjorie Taylor Greene defeated physician John Cowan in a runoff election for the Republican nomination in Georgia's deep-red 14th Congressional District on Tuesday, AP reports.

Why it matters: Greene, a vocal QAnon conspiracy theorist who has been condemned by GOP leaders for making multiple offensive remarks about Black people, Jews and Muslims in Facebook videos, is likely to win a seat in the House come November.
