White House sources think Justice Anthony Kennedy, the Supreme Court's ideological fulcrum, may announce his retirement today, as the justices gather on the bench for the last time this term.

If that happens, Day 158 instantly becomes President Trump's biggest moment.

  • Trump's first Court appointment, of Justice Neil Gorsuch, was a one-for-one ideological swap for the late Justice Antonin Scalia.
  • Replacing Kennedy would be even more historic and consequential: a momentous chance to edge the Court right, since Kennedy is the center of the Court — the one most willing to listen to both sides. On a controversial case, both sides pitch to him. It's been called "Kennedy's Court."
  • No one's predicting: Court watchers say no one knows, and Kennedy has said nothing publicly. He could well wait one more year: The Court buzz is that it'll be this year or next.
  • Lyle Denniston, who has covered the Supreme Court for 58 years, headlines a post on his website, "High drama: Supreme Court term is ending": "[R]umors have continued to make the rounds that ... Kennedy, who will be 81 in July, could reveal plans [today] to end his career. ... The longest serving of the Justices, Kennedy joined the court more than 29 years ago."

Be smart: Few domestic developments could more instantly and decisively change the national conversation — blotting out almost everything else, and vastly reducing the sting for conservatives is healthcare tanks.

A Washington wise man emails: "With two court appointments and maybe one more, Trump's presidency will be consequential even if he has few legislative achievements. This week may well demonstrate both."

Republicans and Dems react to Coney Barrett's Supreme Court confirmation

President Trump said Judge Amy Coney Barrett's Senate confirmation to the Supreme Court and her subsequent taking of the constitutional oath Monday was a "momentous day," as she she vowed to serve "without any fear or favour."

  • But as Republicans applauded the third conservative justice in four years, many Democrats including Speaker Nancy Pelosi (Calif.) warned of consequences to the rush to replace the late Justice Ruth Bader Ginsburg ahead of the Nov. 3 election, with progressives leading calls to expand the court.

In her three decades in science, Jennifer Doudna said she has seen a gradual erosion of trust in the profession, but the recent Nobel Prize winner told "Axios on HBO" that the institution itself has been under assault from the current administration.

  • "I think science is on the ballot," Doudna said in the interview.

Why it matters: That has manifested itself in everything from how the federal government approaches climate change to the pandemic.
