A bipartisan coalition of 24 senators — 12 Republicans and 12 Democrats — has signed on to health care legislation to prop up the individual insurance market and keep premiums down.

As someone who lives with obsessive-compulsive disorder, novelist John Green sometimes feels like his mind is spiraling uncontrollably.

A Syrian general known for his fight against ISIS — and accused in the death of veteran American war correspondent Marie Colvin, who died in shelling in 2012 — is reported to have died Wednesday on the battlefield in Syria's northeastern province of Deir Ezzor.

José Ortíz and Ethan Leder had never met, but they quickly came up with an unconventional plan to help Puerto Rico.

Ortíz and Leder's personalities are similar: both are high energy, do-er types. "It's all about doing stuff" says Leder. "Not just talk," adds Ortíz.

When Hurricane Maria hit, Ortíz, a 47-year-old flooring business owner, says his "brain was completely obsessed with it." He was born in Mayagüez, Puerto Rico and was 11 when his family moved to the Washington, D.C. area. "I was just trying to get in touch with anyone in Puerto Rico to offer help."

Hysteria. Panic.

Oct. 19, 1987, brought the single biggest one-day percentage drop in history — and yes, that includes the 1929 crash that presaged the coming of the Great Depression.

On that frightening Monday three decades ago, the Dow Jones industrial average plunged 508 points — more than 22 percent — to just over 1,700.

You might say George W. Bush wants to make America great again.

In remarks Thursday, he criticized the kind of politics, sentiment and populism that led to President Trump's rise and election — though he never named Trump explicitly.
