* Chris Strohm reports on the latest twist in Robert Mueller’s investigation into Russian meddling in the election:

Russia’s effort to influence U.S. voters through Facebook and other social media is a “red-hot” focus of special counsel Robert Mueller’s investigation into the 2016 election and possible links to President Donald Trump’s associates, according to U.S. officials familiar with the matter.

Mueller’s team of prosecutors and FBI agents is zeroing in on how Russia spread fake and damaging information through social media and is seeking additional evidence from companies like Facebook and Twitter about what happened on their networks, said one of the officials, who asked not to be identified discussing the ongoing investigation.

The ability of foreign nations to use social media to manipulate and influence elections and policy is increasingly seen as the soft underbelly of international espionage, another official said, because it doesn’t involve the theft of state secrets and the U.S. doesn’t have a ready defense to prevent such attacks.

Russia correctly identified one of our greatest weaknesses, which is that many Americans are dumb enough to believe whatever they read on Facebook.

* Kelsey Snell, Mike DeBonis, and Damian Paletta report that all the suspense may soon be over:

The White House and GOP leaders plan to reveal new details of their plan to cut corporate and individual taxes the week of Sept. 25, and they are imploring lawmakers to reach a budget agreement that could smooth its passage, a key lawmaker told his colleagues Wednesday morning.

House Ways and Means Committee Chairman Kevin Brady (R-Tex.) told other House Republicans during a closed-door meeting that they needed to unify or the effort to cut taxes could fail, according to two people in the room.

That was a nod to the GOP’s aborted fight to replace parts of the Affordable Care Act earlier this year, during which the House and Senate tried to pass competing health-care bills, splitting the party and culminating in the effort’s failure. They want a much different outcome in their tax overhaul effort.

Brady told his colleagues that “the stakes are higher than ever that we deliver this year.”

Just think of those poor billionaires looking out mournfully at the ocean from their houses in the Hamptons, wondering, “Will I get my tax cut? Does anyone care about me?”

* Suzy Khimm has the story of Trump’s nominee to be the No. 2 official at FEMA, who had been investigated for charging taxpayers for personal trips, falsifying records, and violating a ban on recently departed officials lobbying their agencies.
