A historian Friday described the historic impact of the Supreme Court's decision in its ruling against President Donald Trump's tariffs — something the nation's founders would have appreciated.
Tim Naftali, CNN's presidential historian and former head of the Nixon Presidential Library, explained why the high court's ruling was an active practice of what the Constitution was intended to do.
"Well, wherever he is, James Madison is smiling today. Tariffs are a tax. The founders decided that taxes should be the responsibility of the Article One branch, which is Congress," Naftali said.
"And today the U.S. Constitution worked as it's supposed to work, which is to keep various parts of the government in check when they overstep constitutional bounds," he added.
The court's decision was also one of many times throughout history that the Supreme Court has pushed back on a president.
"This is a huge moment in American history," Naftali said. "Donald Trump is not the first president to have been disappointed by the court. The courts in the 1930s invalidated Franklin Roosevelt's New Deal. That's what led to the first push to pack the court that was Roosevelt's response to the fact that he was so angry at the court for undermining the New Deal.
"In the end, the court changed, and the New Deal stayed. Richard Nixon was furious at the court for forcing him to turn over the tapes when he lost the case. U.S. v Nixon. Well, the Dobbs decision really unsettled the Biden presidency. And Obama was not happy with Citizens United."
He said it's not new for presidents to be unhappy about a Supreme Court decision, but it is American.
"It's the way that it works. Our system is supposed to work this way every so often. One of the branches is supposed to be disappointed when it can't engage in a power grab that is unconstitutional."
