Trump has plans to decertify the 2015 Iran nuclear deal, according to "people briefed on an emerging White House strategy for Iran," per The Washington Post.

What it means: The deal has eased Iran off sanctions in exchange for a rolled-back nuclear program, so this could set the U.S. on a path to sanction Iran and amp up tensions between Tehran and D.C. And Tehran has said it could start up its nuclear program within days, raising a potential additional nuclear problem for Trump in addition to North Korea. Ultimately, the decision would be kicked to Congress.

The disagreement: Mattis said earlier this week he thought it would be in U.S. security interests to remain in the deal, although today White House Press Secretary Sarah Sanders said Trump's national security team is "supporting" his decision and to expect an announcement in "days." Sanders elaborated that "the president has, as he said, made a decision on this and he'll make that announcement at the appropriate time. The main focus that he has had has been a comprehensive strategy on how to deal with Iran."

Those briefed on the matter told The Washington Post the plans still may change, but keep in mind Trump has been railing against the deal for some time now as a bad deal for the U.S.

In a post to staffers Saturday obtained by Axios, Facebook VP of global affairs Nick Clegg warned the company that worse coverage could be on the way: “We need to steel ourselves for more bad headlines in the coming days, I’m afraid.”

Catch up quick: Roughly two dozen news outlets had agreed to hold stories based on leaked materials from Facebook whistleblower Frances Haugen for Monday publication — but the embargo fell apart Friday night as participating newsrooms posted a batch of articles ahead of the weekend.

A series of powerful "atmospheric river" storms are set dump historic amounts of rainfall across parts of drought-stricken California and the Pacific Northwest from this weekend, forecasters warn.

Why it matters: A strong atmospheric river, packing large amounts of moisture, is predicted to whiplash Northern California from drought to flood.

Inside Biden's Taiwan flubs

Twice this year, President Biden has blurted out commitments that the U.S. is prepared to defend Taiwan against a Chinese invasion — forcing the White House to walk back his statements and leading to confusion over a high-stakes national security policy.

Why it matters: U.S. defense officials have publicly aired their concerns that China will take Taiwan by force in the next four to six years, perhaps sooner. The president's position on this question may soon have real-world, life and death consequences.
