Saudi Arabia's crown prince, Mohammed bin Salman, ordered the arrests of dozens of influential people, including 11 of his royal cousins and Prince Alwaleed bin Talal — the billionaire Saudi investor in Apple, Twitter and the Four Seasons.

  • The big picture: His move, "presented as a crackdown on corruption," appears to be "the most sweeping transformation in the kingdom's governance for more than eight decades," NYT's David Kirkpatrick reports.
  • But, but, but: "Crown Prince Mohammed's haste ... may now come at a price, because the lack of transparency or due process surrounding the anticorruption crackdown is sure to unnerve the same private investors he hopes to attract — including through a planned stock offering of the huge state oil company, Aramco."

Inside the shakeup, via the Times:

  • "With the new detentions, Crown Prince Mohammed ... now appears to have established control over all three Saudi security services — the military, internal security services and national guard."
  • "Apolitical scholars who used to speak freely in cafes now look nervously over their shoulders, as Crown Prince Mohammed has achieved a degree of dominance that no ruler has attained for generations."
  • "It is the coup de grâce of the old system," Chas W. Freeman, a former United States ambassador, told the Times. "Gone. All power has now been concentrated in the hands of Mohammad bin Salman."

One more thing: A helicopter carrying Prince Mansur bin Muqrin, the deputy governor of a Saudi province bordering Yemen, crashed Sunday, and he was killed with other officials on board, the Times reports. The incident is apparently unrelated to the weekend's arrests, and the cause of the crash has not yet been reported.

Sen. Tim Scott (R-S.C.) told reporters on Wednesday that he believes President Trump "misspoke" when he told the far-right "Proud Boys" group to "stand back and stand by" in response to a question about condemning white supremacy at the first presidential debate.

Catch up quick: Moderator Chris Wallace asked Trump on Tuesday, "Are you willing, tonight, to condemn white supremacists and militia groups and to say that they need to stand down?" Trump asked who specifically he should condemn, and then responded, "Proud Boys, stand back and stand by. But I'll tell you what, somebody's got to do something about antifa and the left."

The Commission on Presidential Debates announced Wednesday that it plans to implement changes to rules for the remaining debates, after Tuesday night's head-to-head between Joe Biden and Donald Trump was practically incoherent for most of the night.

What they are saying: "Last night's debate made clear that additional structure should be added to the format of the remaining debates to ensure a more orderly discussion of the issues," the CPD said in a statement.

Trump says he doesn't know who Proud Boys are after telling them to "stand by"

President Trump told reporters on Wednesday that he doesn't know who the Proud Boys are, after saying at the presidential debate last night that the far-right group should "stand back and stand by" in response to a question asking him to condemn white supremacists.

Why it matters: The comments set off outrage and calls for clarification from a number of Republican senators. After being asked several times on Wednesday whether he will condemn white supremacy, Trump responded, "I have always denounced any form — any form of any of that, you have to denounce. But I also — Joe Biden has to say something about antifa."
