"A man has died and his wife is under critical care after the couple, both in their 60s, ingested chloroquine phosphate, an additive commonly used at aquariums to clean fish tanks," which is also part of one of the antimalaria drugs that President Trump has mentioned in recent days, according to Banner Health, the hospital system that treated both patients.

Why it matters: People who attempt to self-medicate risk serious side effects or death, and it's why any messaging about chloroquine and the related hydroxychloroquine should emphasize that these drugs have not been approved to prevent or treat the new coronavirus.

Worth noting: The malaria drug comes in tablet form, but the type the couple used was a toxic substance — not medication.

  • The man's wife told NBC News: "I had it in the house because I used to have koi fish."

Editor's note: The story and headline have been corrected to reflect the fact that the form of chloroquine the couple ingested was used in aquariums (not the medication).

In her first week on the job, Amy Coney Barrett may be deciding which votes to count in the presidential election. By her third week, she’ll be deciding the fate of the Affordable Care Act.

Where it stands: The Senate votes on Barrett’s nomination tomorrow. If she’s confirmed, Chief Justice John Roberts is expected to swear her in at the Supreme Court within hours, an administration official tells Axios.

Texas Democrats beg Biden to spend now

The Biden campaign is rebuffing persistent pleas from Texas Democrats to spend at least $10 million in the Lone Star state, several people familiar with the talks tell Axios.

Why it matters: If Texas — which has 38 electoral votes and is steadily getting more blue, but hasn't backed a Democrat for president since 1976 — flipped to the Biden column, it would be game over. But the RealClearPolitics polling average stubbornly hovers at +2.6 for Trump — and Team Biden appears more focused on closer targets.

Election night in Trumpworld

A luxe election-night watch party at the Trump International Hotel on Pennsylvania Avenue is being planned for President Trump's donors, friends and advisers — but Trump's hand in it is minimal because he's "very superstitious" — people familiar with the plans tell Axios.

The big picture: This "mecca for all things MAGA," as one adviser described it, is one of three hubs where they say Trumpworld will watch returns. The others are the war room at campaign HQ in Rosslyn, Virginia, and the White House residence, where Trump and the first lady will gather close family and advisers before heading to the hotel later that night, the sources said.
