The spread of the coronavirus in China has raised concerns about the pharmaceutical industry's global supply chain, STAT reports.

Between the lines: China produces a large portion of the ingredients used to make drugs. As the coronavirus spreads and sends China increasingly into lockdown, it's causing experts to question whether the supply chain is stable.

By the numbers: 13% of all facilities that make ingredients for drugs sold in the U.S. are located in China, and 85% of medicines in the U.S. strategic national stockpile use some component that comes from China.

Yes, but: Most drugmakers have more than one supplier for the ingredients they need for each medicine.

A federal judge on Tuesday temporarily blocked South Carolina's ban on mask mandates in schools, ruling that it discriminated against students with disabilities and violated the Americans with Disabilities Act.

Why it matters: As mask bans extend to public schools around the country, parents and disability rights activists have sounded alarm bells. The ruling may signal the outcomes of legal fights playing out across the country.

Florida Gov. Ron DeSantis took legal action on Tuesday to try to stop the Biden administration's immigration plans.

Why it matters: The Republican governor, who is running for re-election next year and is possibly eyeing a 2024 presidential bid, is picking a high-profile fight with Biden while re-upping his hardline stance on immigration.

Rep. Ro Khanna (D-Calif.) lambasted Sen. Kyrsten Sinema (D-Ariz.) on Tuesday, saying "it's insane" that "one senator" is blocking attempts to settle on a palatable figure for President Biden's proposed $3.5 trillion budget reconciliation package.

Why it matters: The figure is the linchpin to getting progressive support for the companion $1.2 trillion bipartisan infrastructure package. Khanna's statement reflects broader dissatisfaction among House progressives with Sinema and her fellow holdout, Sen. Joe Manchin (D-W.Va.).
