An earlier version of this story provided an inaccurate figure for the amount of income Donald Trump reported with the Federal Election Commission. The story has been corrected.

At a press conference Wednesday, the lawyer for President-elect Donald Trump invited a comparison to a magnate from another time.

“The business empire built by President-elect Trump over the years is massive, not dissimilar to the fortunes of Nelson Rockefeller,” said Sheri Dillon of the law firm Morgan Lewis. “But at that time, no one was so concerned.”

But the record shows there was concern about Rockefeller.

After being appointed by President Gerald Ford to serve as his vice president in the wake of the Nixon resignation, Rockefeller came before the Senate in September 1974 as an unsuccessful politician who had lost a few runs at the White House.

Rockefeller said he was trying to dispel the “myth” about the Rockefeller family empire, founded by his grandfather, J.D. Rockefeller, who’d started the Standard Oil Co., according to the New York Times.

Rockefeller said he had total holdings of $218 million (or some $1.07 billion in 2016 dollars).

Rockefeller said he had paid a total of $69 million in taxes over his lifetime.

The Times said this revelation “seemed more likely to reinforce the image he was eager to dissipate.”

Not all members of the Senate that day were convinced.

Sen. Robert Byrd, in hostile questioning, called the Rockefeller businesses “an empire.”

Rockefeller tried to fight back, arguing that his family merely had “interests” and not “controlling interests.”

Joseph Rauh, head of the liberal Americans for Democratic Action, warned that if Rockefeller ever became president “every decision” he made would affect his family.

“At 8 o’clock a decision affecting banks, at 9 affecting communications, at 10 affecting airlines, at 11 affecting oil, at noon affecting insurance and so on through the day,” Rauh told the House Judiciary Committee.

G. William Domhoff and Charles Schwartz, professors at the University of California, were invited by Congress to study the Rockefeller family’s interests. They put the total Rockefeller family holdings at $70 billion.

In contrast, Trump’s team wants his businesses to be called an “empire.”

In a financial report filed with the Federal Election Commission, Trump said his income was $557 million and his net worth was in excess of $10 billion. Numerous critics have questioned whether Trump is in fact worth that much.
