The 64-year-old swam 110 miles for 53 hours in shark infested waters but other athletes now want to know did she really swim completely unassisted? Did she rest on a boat? Hold onto a canoe? Was she ever pulled along?
Skeptics speaking to National Geographic and blogging on "The Marathon Swimmers Forum" point to one 9 hour-stretch, when Nyad sped up to more than twice her average speed.
They want her GPS, surface-current, weather, eating and drinking data released to verify her claim of conquering a swim once considered impossible.
Nyad's team promise a point-by-point response.
A security breach, reportedly the worst in thirty years, clearly has police on edge at Buckingham Palace, reports CNN's Erin McLaughlin.
Two men were arrested for allegedly targeting the Queen's main residence, which is packed with priceless works of art and jewelry.
Official say a man scaled a 12 ft. fence and broke through a door while his accomplice waited outside the palace.
On display is a temporary exhibition which is open to the public to celebrate the 60th anniversary of the Queen's coronation that includes a spectacular diamond crown that the Queen can be seen wearing on British stamps and coins.
Though nothing was stolen, no one was hurt in the incident and the Queen is still on vacation at her castle in Scotland, the incident caused local authorities to be on high alert.
Just two days later, London's metro police confronted a would be intruder wandering around the palace gardens, shouted and demanded he identify himself.
The problem was the intruder was actually the Queen's son, Prince Andrew, simply enjoying a walk.
Scotland Yard later apologized to the Prince who took it in stride saying in a statement:
"The police have a difficult job to do balancing security for the Royal Family and deterring intruders. Sometimes they get it wrong."
Two months ago, doctors feared Kali Hardig might not live.
Now for the first time, we're hearing from the young girl who defied all odds with a miraculous recovery from brain-eating amoebas.
CNN's Elizabeth Cohen reports.
Hardig says, I'd "been in the hospital for a long time...a long time."
In July, the 12-year-old went swimming in a lake at a water park in Arkansas and contracted parasitic meningitis, a rare, and usually fatal infection caused by the horrific parasites.
The young girl is only the 3rd person known to have survived this condition in the past 50 years.
Her mom, Traci Hardig, probably saved her daughter's life by acting fast and fighting for the proper treatment. She says, "I feel blessed, I feel just overwhelmed, she's doing wonderful."
White House Deputy National Security Adviser Ben Rhodes responds to lawmakers and critics who say they'd vote against U.S. military action in Syria after a new CNN/ORC poll shows a majority of Americans are against actions whether or not Congress approves the resolution.
Rhodes tells Anchor Chris Cuomo the administration has “no doubt” Assad is responsible for the use of chemical weapons in Damascus.
When asked about the consequences of U.S. action in terms of Syrian retaliation, Rhodes is dismissive.
“It’s simply not in anybody’s interest to invite further strikes from the United States by doing anything. We’re going to make it very clear; we’re prepared for any contingency. Our military can handle whatever comes at us. But the fact of the matter is, we don’t think it’s in the interest of Assad or any of his allies in the region to… test the resolve of the United States by doing something after we take this strike.”
