More recently, Mr. Sanders has come under criticism for his expanding personal wealth.
The website is run by the Center for American Progress Action Fund, the sister organization of the Center for American Progress, a liberal think tank.
On Saturday, Mr. Sanders fired back, accusing the think tank of “using its resources to smear” him and other progressive presidential candidates.
[On Fox News, Mr. Sanders rejected the idea that his wealth was proof of the “American dream.”].
Tax returns released by other Democratic presidential candidates have shown that they also earned more than a vast majority of American households in recent years.
Former Representative Beto O’Rourke of Texas also disclosed 10 years of tax returns on Monday, though not his 2018 return.
Ms. O’Rourke collects dividends and interest from family partnerships established by her father, the real estate investor William D. Sanders (no relation to Bernie Sanders). »
