Kimberly-Clark Corp. shares fell the most in a quarter century after agreeing to buy Kenvue Inc., whose biggest product, Tylenol, is in the crosshairs of the White House.

Not long after President Trump made his statement, Kenvue and Johnson & Johnson got into another complicated legal mess when the Republican state of Texas sued them. The complaint says that the companies didn’t tell people about the possible risks of taking acetaminophen while pregnant.

Kimberly-Clark is buying Tylenol maker Kenvue in a cash and stock deal worth about $48.7 billion, creating a massive consumer health goods company.
