Melinda Gates and Sam Altman are among the first U.S. billionaires to comment on the death of Alex Pretti, days after the 37-year-old nurse became the second American citizen to be killed by federal agencies this month in Minnesota.

In a post on X, Gates, the ex-wife of Bill Gates, called the killings of Pretti and Renee Good “unconscionable” and said they were weighing heavily on “so many of our hearts.”

She said Americans should not have to be afraid of losing their life while peacefully protesting, writing, “There is nothing more American than exercising our rights and holding our government accountable. Our democracy depends on it.”
