President Trump is cutting against historical and political norms on a trifecta of big issues at the heart of U.S. domestic, economic and security policy:

• He is pushing to kill "Obamacare" through the courts over the objection of his own attorney general and top GOP congressional leaders. 
• The White House is publicly pushing the Fed to cut interest rates, something prior administrations never contemplated doing.
• The president is again publicly threatening to close ports of entry on the U.S. southern border. "I'm not playing games," Trump said Friday in Florida.
• The State Department said the U.S. will cut off aid to the Central American countries of El Salvador, Guatemala and Honduras — the Northern Triangle. Trump said: "No money goes there anymore. ... We stopped payment." The WashPost reports that the escalation involves hundreds of millions of dollars.

A Trump administration official familiar with the situation told Jonathan Swan that the president "is definitely serious about" closing the border and "has talked about it quite a few times and wanted to do it several times."

• The source said Trump's idea would mean that day laborers could cross the border, but that it would otherwise be a "total no entry." 

But administration officials privately say it's unlikely Trump will follow through on his threat, and acknowledge that they're nowhere near prepared to execute on such a radical plan on the president's threatened timeline of this week.

• The widespread view within the White House and at the Department of Homeland Security is that it's a terrible and unworkable idea.
• Trump administration officials have been discussing the impracticalities, such as U.S. citizens coming and going across the border.
• But Trump wants it. So "it's being looked into, what it could and would look like," the administration official said.

The backdrop: A swelling number of asylum seekers from Central America is straining the immigration system to the breaking point, AP reports.

• Hundreds of officers who usually screen cargo and vehicles at ports of entry have been reassigned to help manage migrants.
• An administration official told Swan: "This is the result of a broken immigration system that fails the nation and fails to effectively promote any of the goals it should — economic prosperity, public safety and national security, protecting vulnerable populations, and welcoming legal immigrants."

Gavin de Becker, a celebrity security consultant who has had Jeff Bezos as a client of 22 years, makes a bombshell allegation about how Bezos' texts and pics leaked to the National Enquirer:

• "Our investigators and several experts concluded with high confidence that the Saudis had access to Bezos’ phone, and gained private information," De Becker writes in a first-person piece for the Daily Beast.
• "[T]he Saudi government has been intent on harming Jeff Bezos since last October, when [the WashPost, which he owns,] began its relentless coverage of [journalist Jamal] Khashoggi’s murder."

Facebook CEO Mark Zuckerberg said in an op-ed published yesterday that entities outside of Facebook should set the standards for the "distribution of harmful content" online and hold platforms like his accountable.

• Why it matters, from Axios' David McCabe and Gigi Sukin: Zuckerberg is trying to shape the terms of the multi-front debate over its collection of user data and massive influence over information.

Zuckerberg said legislation on online political advertising "should be updated to reflect the reality of the threats and set standards for the whole industry."

• "Facebook already publishes transparency reports on how effectively we’re removing harmful content. I believe every major Internet service should do this quarterly," Zuckerberg wrote.

Zuckerberg's piece was published in today's Washington Post (print headline: "The Internet needs new rules"), Frankfurter Allgemeine Sonntagszeitung (Germany), Sunday Independent (Ireland) and Le Journal du Dimanche (France).

• Sharing the Post piece on her Facebook page, COO Sheryl Sandberg wrote: "We know we have more to do to keep people safe on our platforms."

"It is harder than ever to get into a top-tier college," the N.Y. Times reports:

• "The rate at Harvard fell to 4.5 percent this year, down slightly from 4.6 percent last year. It also increased its share of Asian-American admits to 25.4 percent from 22.7 percent, at a time when it is waiting for a decision in a lawsuit accusing it of discriminating against Asian-American applicants."
• "Yale’s admission rate sank to 5.91 percent from 6.31 percent last year, or 2,178 students out of a record-high pool of 36,843."

"Last year, Stanford ... announced that it would no longer release admissions data to the public, only to the federal government."

• "Last year, its acceptance rate was 4.3 percent for the Class of 2022, below those of Harvard and Yale."

After NASA canceled the first all-female spacewalk for lack of medium-size spacesuits, working women on Earth shared their own stories about male-centered equipment, the WashPost's Jena McGregor reports:

• "[W]omen told of giant overalls, wading boots that were the wrong size, oversize gloves that kept them from being nimble, a lack of bulletproof vests that accommodated their chest sizes and a dearth of petite-size personal protective equipment at construction sites."

"I work in an ambulance, where everything from the driver's seat to the latch on the cot is made for your average sized man," a Canadian woman tweeted.
