Here's how the Las Vegas shooting compares to all of the U.S. mass shooting events since 2013, using data from the Gun Violence Archive. The group uses a broad definition of mass shootings: any reported incident where at least four people where shot or killed — excluding the shooter — at the same time and location.

A federal spending deal reached in Congress Monday is set to allocate $25 million toward gun violence research at the Centers for Disease Control and Prevention as well as the National Institutes of Health.
Why it matters: Scientific reports show that a lack of data on gun violence has delayed pivotal reforms despite persistent mass shootings. The Dickey Amendment, which states that funds provided to the CDC may not be used to "advocate or promote gun control," has complicated efforts to conduct gun violence research since it was passed in 1996.

Attorney General William Barr said Monday that the shooting at Pensacola Naval Air Station that killed three service members last month was an "act of terrorism" and that the Saudi gunman was determined to have been "motivated by jihadist ideology" following a criminal investigation.
The big picture: The attack, perpetrated by a member of the Royal Saudi Air Force enrolled in a training program at the base, prompted a review that led the military to expel more than a dozen Saudi trainees, per CNN. Though none were have found to have aided the gunman in the Pensacola incident, some were found to have connections to extremist movements.

President Trump tweeted his praise Monday for the parishioners who returned fire on a gunman on a gunman who entered their church in Fort Worth, Texas, and the state's gun laws.
"Our prayers are with the families of the victims and the congregation of yesterday’s church attack. It was over in 6 seconds thanks to the brave parishioners who acted to protect 242 fellow worshippers. Lives were saved by these heroes, and Texas laws allowing them to carry arms!"
