* Ashley Parker and Jenna Johnson report that President Trump really brought the empathy to Puerto Rico today:

President Trump on Tuesday told Puerto Rican officials they should feel “very proud” they haven’t lost hundreds of lives like in “a real catastrophe like Katrina,” while adding that the devastated island territory has thrown the nation’s budget “a little out of whack.”

Trump’s remarks came as he touched down in San Juan for his first visit to Puerto Rico since the storm ravaged the island nearly two weeks ago. He has faced criticism for the slow federal response to the natural disaster, although he praised himself earlier in the day for his administration’s “great job” and “A-plus” response to Hurricane Maria.

“Every death is a horror, but if you look at a real catastrophe like Katrina, and you look at the tremendous — hundreds and hundreds and hundreds of people that died, and you look at what happened here, with really a storm that was just totally overpowering, nobody’s ever seen anything like this,” Trump said, before turning to a local official to ask how many people had died in storm. “What is your death count as of this moment? 17? 16 people certified, 16 people versus in the thousands.”

Trump then praised officials in the room over the death toll.

It’s that tender human touch that makes him such a great leader. He actually said to a family of hurricane victims, “Have a good time.” I kid you not.

* Mike DeBonis and Kelsey Snell report that the massacre in Las Vegas has had a small effect on federal legislation:

House Speaker Paul D. Ryan said Tuesday that Republican leaders have no plans to advance a bill that would make it easier for Americans to buy gun silencers.

The focus on the legislation, which passed a House committee last month, was magnified Monday after the shooting in Las Vegas on Sunday night left at least 59 dead and hundreds injured.

“That bill is not scheduled now; I don’t know when it’s going to be scheduled,” said Ryan (R-Wis.). “Right now we’re focused on passing our budget.”

The Las Vegas shooting is the latest incident of mass violence to put Republican lawmakers on the defensive over their opposition to new gun restrictions — and, in some cases, their efforts to eliminate existing ones.

It’s almost as though Ryan felt a momentary bit of shame. Go figure.
