"If she gets to pick her judges, nothing you can do, folks," Trump told a North Carolina rally. "Although the second amendment people, maybe there is, I don't know. But I'll tell you what, that will be a horrible day." Trump said he was merely encouraging gun rights advocates to be politically involved. This is Trump at his lowest yet, writes Lucia Graves. Donald Trump hints at assassination of Hillary Clinton by gun rights supporters Phelps adds to gold medal haul If Michael Phelps were a country, he would be 39th on the all-time Olympic gold medal table. The American swimmer's astonishing career tally of 21 Olympic golds came with dual wins last night in the 200m butterfly and in the 4x200m freestyle relay at the Rio Olympics. "I came into the pool tonight with a mission and the mission was accomplished," Phelps said. "I'm looking forward to the rest of the week and I'm not even halfway done yet." The swimmer, who has 25 medals in all, has three more opportunities in Rio, his final Olympics, in the 100m butterfly, 4x100m medley relay and 200m individual medley. Here is our summary of day five in Rio. Meanwhile the credibility of Olympic swimming, already suffering from spats and doping scandals, has been further damaged by serious discrepancies in the entry times of a number of competitors, Andy Bull reports. If Michael Phelps were a country, he would be 39th on all-time Olympics gold medal table Simone Biles gets going The astonishing 19-year-old US gymnast finished with the highest individual scores in the vault, the balance beam and the floor exercise to lead the US gymnastics team to a record-breaking win. Biles entered these Olympics already widely hailed as the most talented gymnast ever, writes Bryan Graham. "By the end of the individual event finals next week she could have become the first woman to win five of them in one Games." Biles said afterwards: "It felt kind of normal ... It didn't even feel like the Olympics because we were just so ready." Here, we look at how the US women's gymnastic team swept to gold. Simone Biles helps USA to team gymnastics gold – and targets four more Paul Ryan beats 'mini-Donald Trump' Paul Ryan, the Republican party's most senior elected official, has survived an insurgent challenge in his own backyard from an outsider candidate dubbed a "mini-Donald Trump". The House speaker comprehensively beat maverick businessman Paul Nehlen in Tuesday's Republican primary in Wisconsin's 1st congressional district. "We knew we were going to do well. The outcome is exactly what we were hoping for and what we were expecting," Ryan said. Paul Ryan beats outsider 'mini-Donald Trump' challenger in Wisconsin primary Gunshots in Ferguson Gunfire broke out on the second anniversary of Michael Brown's death after a protester was knocked down by a car during a demonstration in Ferguson, Missouri. Police responded to reports of gunfire but had found no evidence that anyone had been struck, said Ferguson spokesman Jeff Small. A video posted online shows a car hitting a young man who was standing in the road, knocking him to the kerb. Onlookers gather around and call for help. About a minute later, gunfire erupts. In Baltimore, a US justice department report to be released on Wednesday will say the police department regularly conducted unlawful stops and used excessive force on residents of the city. Gunshots in Ferguson after car hits protester on Michael Brown anniversary The lake that left Eagle Lake, in northern California, is one of the largest in the state. It has fallen around 15ft since 1999, a decline thought to have been exacerbated by climate change. The main lakeside community of Spalding is dotted with "for sale" signs, and its tidy streets are empty. The waterfront is now a meadow, and the lake has receded to a thin strip in the distance, like an alluring mirage. There are no longer any restaurants, and the general store is shuttered. Misfortune is everywhere. Is climate change to blame? Alastair Gee reports. The lake that left town: why is this California community drying up? Love and Rockets rides again Rolling Stone ranked Love and Rockets as the greatest non-superhero graphic novel of all time, likening it to the Clash, REM and Run-DMC. Time magazine included its creators, the Latino-American brothers Jaime and Gilbert Hernandez, in its top 100 21st century innovators. Next month, the revered comic book about California punks will be back on newsstands on its 35th anniversary, with characters looking back on their lives and varying fortunes. Love and Rockets rides again: 'we influenced a whole lot of cartoonists' In case you missed it … Monsters of art From Da Vinci's live animal mashups to a macabre giant skeleton, a new book celebrates some of scariest beast in art. Monsters: A Bestiary of the Bizarre shows Leonardo da Vinci used a technique deployed by many other artists: take the most interesting bits from bats, dragonflies, lizards, birds, snakes and other animals and splice them together. But the most terrifying monster, Jonathan Jones points out, is always us – a skeleton, stripped of flesh, returned from the grave – and more frightening than any dragon.
