Siren, a maker of "smart socks" designed for early detection of diabetic ulcers, yesterday announced nearly $12 million in venture funding led by Anathem Ventures.

Why it matters: This plays into the burgeoning remote health care trend, as people at risk of diabetic ulcers typically require regular foot temperature checks from podiatrists.

  • It's also a twist on a recent VC legal drama between Anathem founder Crystal McKellar and her former firm, Mithril Capital.

The company: Siren continuously monitors the temperature on the bottoms of a user's feet, and transmits that data to an app that's available to both the patient and physician.

  • The connected "visits" are reimbursable under Medicare, and basically act as an early warning system to stave off something that can result in hospitalizations and, at worst, amputations.
  • Expect to see a surge in these sorts of deals. Including from Anathem, which just backed FocusMotion, a connected recovery system for patients who've undergone orthopedic surgery.

The legal drama: McKellar previously was general counsel for Mithril, a growth equity firm co-founded by Peter Thiel. She also was a whistleblower, informing a Mithril portfolio company and the FBI about alleged financial misconduct.

  • Mithril sued McKellar, whom some of you might remember as "Becky Slater" from The Wonder Years. She countersued.
  • The two sides quietly dismissed their complaints, although a California court document suggests they subsequently entered arbitration.

Notable in McKellar's complaint was a claim that Peter Thiel was horrified by the goings-on at Mithril, going so far as to consider shutting the firm down.

  • Thiel hasn't publicly commented on the dispute, but the Siren deal might hint at his sentiments. His better-known firm, Founders Fund, was an existing Siren investor and re-upped in this new round, knowing that McKellar was lead investor via Anathem.

McKellar tells Axios: "My parents raised me to do the right thing always, and when you witness your employer engaging in fraud you've got to do something to protect your investors. ... Peter is great. I have a ton of respect for him and am thrilled to be investing alongside him."

Bill Clinton slams McConnell and Trump: "Their first value is power"

Former President Bill Clinton on Sunday called Senate Majority Leader Mitch McConnell's (R-Ky.) vow to fill Ruth Bader Ginsburg's vacant Supreme Court seat before the next presidential inauguration "superficially hypocritical."

The big picture: Clinton, who nominated Ginsburg to the court in 1993, declined to say whether he thinks Democrats should respond by adding more justices if they take back the Senate and the White House in November. Instead, he called on Republicans to "remember the example Abraham Lincoln set" by not confirming a justice in an election year.

Pelosi: Trump wants to "crush" ACA with Ginsburg replacement

House Speaker Nancy Pelosi said on ABC's "This Week" on Sunday that President Trump is rushing to replace the late Supreme Court Justice Ruth Bader Ginsburg because he "wants to crush the Affordable Care Act."

Why it matters: Pelosi wants to steer the conversation around the potential Ginsburg replacement to health care, which polls show is a top issue for voters, especially amid the coronavirus pandemic. The Trump administration has urged the courts to strike down the law, and with it, protections for millions with pre-existing conditions.

Democrats' Armageddon option

Furious Democrats are considering total war — profound changes to two branches of government, and even adding stars to the flag — if Republicans jam through a Supreme Court nominee then lose control of the Senate.

On the table: Adding Supreme Court justices ... eliminating the Senate's 60-vote threshold to end filibusters ... and statehood for D.C. and Puerto Rico. "If he holds a vote in 2020, we pack the court in 2021," Rep. Joe Kennedy III (D-Mass.) tweeted.
