Tiger triumphant: ‘It feels like I’ve come full circle’

More than a decade since he last won a major, and following years of personal problems and potentially career-ending health issues, Tiger Woods donned the green jacket at Augusta National on Sunday after claiming his fifth Masters title by a stroke. His extraordinary comeback was witnessed by his two children, 22 years after his father watched him win his first Masters. “It feels like I’ve come full circle,” Woods said afterwards.

Major achievement. Woods has now won 15 majors. He was the youngest player ever to win the Masters in 1997, aged 21. Only one other player, Jack Nicklaus, has more Masters titles.

Back from oblivion. The win comes exactly two years since Woods told friends, “I’m done”, before a fourth back surgery resolved a spinal problem that had left him barely able to walk.

Spike in threats against Ilhan Omar since Trump tweet

The Muslim Minnesota congresswoman Ilhan Omar says she has experienced a sharp rise in death threats since Donald Trump accused her of downplaying the September 11 attacks. Trump tweeted a video that spliced 9/11 footage with Omar’s remarks at a recent Council on American-Islamic Relations event. Many Democrats have characterised the president’s focus on Omar as dangerous racist bullying, while the White House press secretary, Sarah Sanders, insisted: “It’s a good thing the president is calling her out.”

Post boycott. A group of Yemeni bodega owners have boycotted the New York Post after it published a front page featuring an image of the 9/11 World Trade Center attack with a quote from Omar.

9/11 widow. Alissa Torres, who lost her husband on 9/11, says the controversy over Omar is pointless. “I am outraged that there is more outrage directed against Omar than there is against the undermining of national security systems that were put in place after 9/11,” she said.

‘Mayor Pete’ formally launches 2020 presidential campaign

Pete Buttigieg, the 37-year-old mayor of South Bend, Indiana – and the early, breakout star of the Democratic presidential primary – formally launched his 2020 campaign with a rally in his hometown on Sunday. The gay Rhodes scholar and Afghanistan veteran acknowledged the “audacity of doing this as a midwestern millennial mayor”, but said: “We live in a moment that compels us each to act … It’s not just about winning an election. It’s about winning an era.”

Chasten Buttigieg. Buttigieg was joined on stage by his husband, Chasten, now a social media star in his own right. Their marriage is being seen as an implicit rebuke to Mike Pence, the vice-president and a former governor of Indiana.

Ecuador accuses Assange of using embassy for spying

The president of Ecuador, Lenín Moreno, has told the Guardian that Julian Assange repeatedly violated his asylum conditions and tried to use the Ecuadorian embassy in London as a “centre for spying” during his seven-year stay there, which ended with his expulsion and arrest by UK police on Thursday. The WikiLeaks founder faces up to 12 months in prison for breaching his bail conditions by fleeing to the embassy in 2012 to avoid extradition to Sweden on rape charges, which he denies.

Leftwing support. Assange now faces the threat of extradition to the US to face hacking conspiracy charges, but Nesrine Malik says the left’s apparent disregard for the Swedish claims of rape and sexual assault is blinkered and dishonest.

The man who self-immolated for climate change

Last April, David Buckel, a retired gay rights lawyer from Brooklyn, set himself on fire in Prospect Park to draw attention to humanity’s passivity in the face of manmade climate change. J Oliver Conroy asks whether Buckel’s death made the difference he hoped it would.

Amazon develops a headache in Nashville

Amazon’s search for a new HQ has already seen the firm chased out of New York City. Now a deal with Nashville to build an office complex in return for $100m-plus in subsidies is drawing the ire of libertarians and union-backed activists alike, as Dominic Rushe reports.

The comic nakedly defying Chinese censors

When printers in China told the Beijing comic artist Yan Cong they would not publish any books featuring nudity, he responded with an anthology where every main character is nude. Now, Naked Body is to be released in English. Noah Berlatsky spoke to its publisher.

Opinion

The political class is unwilling and unable to address the vast existential predicament of catastrophic climate change, says George Monbiot. Our only hope for action is mass civil disobedience.

Those who govern the nation and shape of public discourse cannot be trusted with the preservation of life on Earth. There is no benign authority preserving us from harm. No one is coming to save us. None of us can justifiably avoid the call to come together to save ourselves.

Sport

Jürgen Klopp said he was “blown away” by the Mohamed Salah strike that put Liverpool 2-0 up against Chelsea on Sunday, and ahead of Manchester City in the Premier League title race. But City’s 3-1 win over Crystal Palace kept them in the running, and with a game in hand.

On Monday at 3.09pm, the city of Liverpool will observe a minute’s silence to mark the 30th anniversary of the Hillsborough disaster, when 96 men, women and children were killed in a stadium crush during an FA Cup semi-final.
