Asked by Rep. Mike Quigley (D-Ill.) to react to quotes by President Trump and Donald Trump Jr. during the 2016 campaign praising stolen material published by WikiLeaks, special counsel Robert Mueller responded: "Problematic is an understatement."

Why it matters: Throughout his testimony, Mueller has been reluctant to answer questions that stray outside the contents of his 450-page report. His sharp criticism of Trump's praise of WikiLeaks, which he described as an "hostile intelligence service" whose founder Julian Assange is under indictment, is a rare rebuke of the president.

The exchange:

  • Quigley: "This is Donald Trump, Oct. 10, 2016: 'I love Wikileaks. This Wikileaks stuff is unbelievable. It tells you the inner heart. You got to read it.' Donald Trump, Oct. 12, 2016: 'This Wikileaks is like a treasure trove.' Donald Trump, Oct. 31, 2016: 'Boy, I love reading those Wikileaks.' ... How do you react to it?"
  • Mueller: "Well, problematic is an understatement in terms of giving some hope or boost to what is illegal activity."
  • Rep. Quigley: "And Donald Trump Jr. had direct electronic communications with WikiLeaks. On October 3, 2016, WikiLeaks sent another direct message to Trump Jr., asking 'you guys to help disseminate a link alleging candidate Clinton had advocated a drone to attack Julian Assange.' Trump Jr. responded that he had already done so. Same question. This behavior, at the very least, disturbing?"
  • Mueller: "Disturbing and also subject to investigation."

The story of American businesses in the coronavirus pandemic is a tale of two markets — one made up of tech firms and online retailers as winners awash in capital, and another of brick-and-mortar mom-and-pop shops that is collapsing.

Why it matters: The coronavirus pandemic has created an environment where losing industries like traditional retail and hospitality as well as a sizable portion of firms owned by women, immigrants and people of color are wiped out and may be gone for good.

Millions of angry gamers may soon join the chorus of voices calling for an antitrust crackdown on Apple, as the iPhone giant faces a new lawsuit and PR blitz from Epic Games, maker of mega-hit Fortnite.

Why it matters: Apple is one of several Big Tech firms accused of violating the spirit, if not the letter, of antitrust law. A high-profile lawsuit could become a roadmap for either building a case against tech titans under existing antitrust laws or writing new ones better suited to the digital economy.

Survey: Fears grow about Social Security’s future

Data: AARP survey of 1,441 U.S. adults conducted July 14–27, 2020 a ±3.4% margin of error at the 95% confidence level; Chart: Naema Ahmed/Axios

Younger Americans are increasingly concerned that Social Security won't be enough to wholly fall back on once they retire, according to a survey conducted by AARP — in honor of today's 85th anniversary of the program — given first to Axios.

Why it matters: Young people's concerns about financial insecurity once they're on a restricted income are rising — and that generation is worried the program, which currently pays out to 65 million beneficiaries, won't be enough to sustain them.
