Presidents are routinely forced to confront tragedies at home and around the world, often judged by their ability to show empathy and help their fellow Americans begin the process of healing.
Rarely, though, are there two of those kinds of moments in as many days.
In a few hours,
VEGAS, GUNS AND WHAT'S NEXT
The president will meet with law enforcement, first responders and the families of victims of Sunday night's mass shooting. On Monday, he called the murders and woundings "an act of pure evil" and led top officials in a brief moment of silence.
Our team of Times journalists is keeping a close eye with live updates on the investigation and what's known about the shooter, including late word on Tuesday about a detailed surveillance system set up near his room at the Mandalay Bay resort and the arrival in Los Angeles of the alleged gunman's girlfriend.
We're also telling the stories of some of the victims.
Trump will likely try to steer clear of talking about gun control and gun violence, a debate that the shooting has again brought back into focus across the country.
For Nevadans, these are familiar topics. Last year, the state's voters narrowly passed a ballot measure requiring most private buyers and sellers of guns to participate in a background check through a licensed dealer.
And for many, the 2nd Amendment is at the core of the debate. Should it be re-imagined for modern times? We're letting you have your say.

THE PRESIDENT AND PUERTO RICO
Trump spent a few hours on Tuesday touring parts of Puerto Rico that suffered extensive damage from Hurricane Maria. And he insisted his administration was doing a solid job, while also weighing in with an odd quip about a subject he's brought up before on Twitter.
The storm's aftermath has given the island more time in the spotlight than it's had in years and has reminded a lot of people that Puerto Rico would like to be the nation's 51st state.
It's also left some on the U.S. mainland to sort out just how American this U.S. territory really is.
