- An investigation by the Daily Mirror and The Guardian found Cummings had traveled 260 miles in April to visit his parents in Durham along with his wife and son while exhibiting coronavirus symptoms, breaking the country's guidelines in the process.
- Cummings argued that the trip was necessary because "none of our usual child care options were available" in London amid the pandemic while both he and his wife both potentially had the virus.
- Asked by the BBC's Laura Kuenssberg if he wanted to offer an apology to U.K. citizens who did not have the resources to act as he did, Cummings said, "I think that I behaved reasonably." Cummings later said he has not offered his resignation to Johnson.
The state of play: Cummings said he had to go to Durham because he was "worried about the possibility of my wife and child at home all day," insinuating that media reports about his opposition to lockdown guidelines — which he denied — made his home "a target."
- He noted that he specifically did not clear his decision to travel with Johnson. He added that he didn't know if he should have told the prime minister earlier, saying he has to "protect his time."
- Cummings also said that a side trip to Barnard Castle — a key unanswered question in media reports — was to test his eyesight after his sickness before undertaking the drive back to London.
The backdrop: Johnson stood behind Cummings during a press conference on Sunday, saying that he traveled to find child care "at a moment when both he and his wife were about to be incapacitated" and that he "followed the instincts of every father and every parent" in doing so.
- At a press conference after Cummings answered questions Monday, Johnson reiterated his support and said "people will have to make their minds up" about what to think about his chief adviser's actions.
Why it matters: Cummings, widely viewed as the architect of the Brexit campaign, is a highly polarizing figure in British politics.
- Calls for his resignation grew over the weekend — even among members of Johnson's own Conservative Party and typically sympathetic press outlets — due to the hypocrisy of a top adviser breaking the stringent rules that the government had long stressed were mandatory.
- The Daily Mail's front page on Monday screamed: "WHAT PLANET ARE THEY ON?"
The big picture: The U.K. has been a coronavirus epicenter in Europe with more than 260,000 confirmed cases and 36,000 deaths as of Monday, per Johns Hopkins data.
