On Tuesday, the Supreme Court ruled 5-4, along ideological lines, that the family of a Mexican teenager who was killed across the southern border by a U.S. border agent cannot sue for damages.

Why it matters: The court’s decision avoids inviting more lawsuits from foreign nationals against U.S. law enforcement. The court noted in its opinion that “a cross-border shooting claim has foreign relations and national security implications.”

Bernie Sanders is poised to become an economic scapegoat for both the White House and Corporate America, assuming that Sanders comes through Super Tuesday unscathed.

The big picture: If the U.S. economy remains strong, President Trump and CEOs will claim credit (as they've been doing for three years). If it turns sour, they'll blame Bernie (even though it's a largely baseless charge).

President Trump on Monday acknowledged the existence of assembled lists of government officials that his administration plans to oust and replace with trusted pro-Trump people, which were first reported by Axios' Jonathan Swan.

What he's saying: “I don’t think it's a big problem. I don’t think it's very many people,” Trump said during a press conference in India, adding he wants “people who are good for the country, loyal to the country.”

The Trump White House and its allies, over the past 18 months, assembled detailed lists of disloyal government officials to oust — and trusted pro-Trump people to replace them — according to more than a dozen sources familiar with the effort who spoke to Axios.

Driving the news: By the time President Trump instructed his 29-year-old former body man and new head of presidential personnel to rid his government of anti-Trump officials, he'd gathered reams of material to support his suspicions.

Former U.S. ambassador to Ukraine Marie Yovanovitch has signed a book deal with Houghton Mifflin Harcourt, the publisher told AP on Friday.

Details: The untitled memoir will detail the experiences of the career diplomat from Somalia to Kyiv before she returned to Washington, D.C.

45% of Republicans — a plurality — support President Trump pardoning Roger Stone, who was sentenced this week to 40 months in prison for crimes unearthed by the Mueller investigation, according to a YouGov poll.

Why it matters: While it's still not clear whether Trump will actually move to pardon Stone, the fact that he has a plurality of his party on board regarding the issue should only serve to enforce the president's growing sense of self-confidence following his impeachment acquittal.

President Trump said in a Friday tweet that a briefing by a top election-security official before the House Intelligence Committee last week on Russia's attempts to interfere in the 2020 election was a "misinformation campaign ... launched by Democrats in Congress."

Why it matters: Trump, who was reportedly infuriated by the event, has made moves in recent days to ensure that administration jobs are held by those loyal to him — notably at the Office of the Director of National Intelligence, which led the briefing despite Trump's assertion that it was headed by congressional Democrats.

Johnny McEntee called in White House liaisons from cabinet agencies for an introductory meeting Thursday, in which he asked them to identify political appointees across the U.S. government who are believed to be anti-Trump, three sources familiar with the meeting tell Axios.

Behind the scenes: McEntee, a 29-year-old former body man to Trump who was fired in 2018 by then-Chief of Staff John Kelly but recently rehired — and promoted to head the presidential personnel office — foreshadowed sweeping personnel changes across government.

President Trump told reporters on Air Force One Thursday night that he was considering nominating Rep. Doug Collins (R-Ga.) to be his next director of national intelligence, but Collins rebuffed that offer during an appearance on Fox Business' "Mornings with Maria" on Friday.

The state of play: Trump previously hinted he would intervene in the Senate race between Collins and Sen. Kelly Loeffler (R-Ga.). The heated primary race between Collins and Loeffler has raised concerns among Republicans that Democrats could potentially win the special election for the Senate seat, the Atlanta Journal-Constitution writes.

By picking Ambassador Richard Grenell to be acting director of national intelligence, President Trump has slotted a pro-Trump warrior into the ultimate apolitical role.

What they're saying: James Clapper, the longest-serving DNI (2010-2017), tells Axios it's "very worrisome installing a partisan with no real intelligence experience in this position."
