The Note: Facebook's self-regulation failure

It's a critical period for Silicon Valley and its relationship with Washington.

The TAKE with Rick Klein

The two days of congressional hearings Zuckerberg is set to experience could mark a pivot point in how big tech interacts with federal policymakers.

The era of self-regulating benign neglect looks to be ending in apparent failure, with a massive data scandal and blaring warning signs that Russia is again using information warfare to meddle in an election.

Zuckerberg will have to endure a loud few days of lawmaker venting. But what happens next – as Congress and a sometimes unpredictable administration look to balance privacy, connectivity, and the free market – will echo for far longer.

The RUNDOWN with MaryAlice Parks

Speaking to reporters Monday, Trump said he heard someone “broke into” Cohen’s offices, making it sound as if law enforcement agents were not just wrong but acting criminally.

Obviously, though, the fact that federal prosecutors were able to get a search warrant like this means they persuaded a judge that there could be evidence of criminal wrongdoing.

Last week, the president cemented his relationship with Cohen, punting all inquiries about a payment to an adult film star - to him. “Michael’s my attorney, and you’ll have to ask Michael,” he said on Air Force One.

According to Cohen’s lawyer, the FBI officials seized sensitive attorney-client communications during their raids. If true, that’s a move not done lightly, nor likely by mistake, especially when the client is presumably not a normal one but president of the United States.

The TIP with Christopher Donato

The SEC action would remove seven U.S. Senate candidates “who were properly challenged and found not to meet the requirements to be determined a bona fide Republican.” The state’s GOP bylaws require that candidates be active members of the party and have voted in three of the last four Republican primaries in their county of residence.

While Corker’s announcement wasn’t an explicit endorsement, Blackburn retweeted Corker and added that she appreciates his support.
