Former Vice President Joe Biden is a "healthy, vigorous, 77-year-old male who is fit to successfully execute the duties of the Presidency," a doctor's report released by his 2020 campaign on Tuesday says.

The big picture: Top candidates Biden, Elizabeth Warren and Bernie Sanders are each older than 70 years old. They promised on the debate stage in September to release their medical and surgical histories before the primary's first votes are cast.

  • Warren has also released hers, while Sanders, who had a heart attack earlier this year, said he'd release his records "at the appropriate time."

Details: Biden had an intracranial hemorrhage from a cerebral aneurysm in 1988. A 2014 CT angiogram showed no recurrence. He has no history of diabetes, tobacco use or cancer other than localized non-melanoma skin cancers.

Biden's records from 2009 to 2017 show he's been treated for...

  • Non-valvular atrial fibrillation, but this does not require medication or treatments.
  • Hyperlipidemia, which is treated with Crestor.
  • Gastroesophageal reflux, which makes him clear his throat frequently. He uses over-the-counter Nexium.
  • Seasonal allergies he's had most of his life.

The bottom line: About 50% of Democrats told Pew Research Center that they want a president in their 50s. Former President Jimmy Carter has said he couldn't have managed the role of commander in chief at 80 years old.

  • President Trump is 73 and became the oldest first-term president when inaugurated.

National Oceanic and Atmospheric Administration forecasters warned Thursday of the potential for an "extremely active" hurricane season in the Atlantic.

New York Attorney General Letitia James filed a lawsuit Thursday to dissolve the National Rifle Association, alleging the group committed fraud by diverting roughly $64 million in charitable donations over three years to support reckless spending by its executives.

Why it matters: The NRA is the most powerful gun lobby in the country and receives a huge amount in donations each year, but New York's investigation claims that CEO Wayne LePierre and other top leaders undermined the organization's mission for their own personal benefit.

How 2,750 tons of ammonium nitrate were stranded in Beirut

On Sep. 23, 2013, a Russian-owned, Moldovan-flagged ship departed Georgia en route to Mozambique bearing 2,750 tons of ammonium nitrate, a material used in fertilizer as well as explosives.

Why it matters: The Rhosus made an unscheduled stop in Beirut, apparently due to engine problems. The ammonium nitrate never left the port, but destroyed it nearly seven years later, along with much of the city.
