Student loan debt may be one of the only topics on which Donald Trump and Sen. Elizabeth Warren agree.

During a Twitter chat Monday, the real estate mogul and Republican candidate for president accused the government of profiting off student loans, in response to a question about how he would solve the student debt crisis.

“Right now, it’s not fair,” Trump said in a Vine. “It’s one of the only places frankly where our country actually makes money and they make a lot of money and that should not take place. We’re going to make it really good for the student.”

Trump’s take, which he’s mentioned a few other times on the campaign trail, isn’t unique. Warren, a Democrat from Massachusetts, has repeatedly criticized the government for making money off student loans, writing in a letter with five other senators earlier this year that the Department of Education is “squeezing students who are struggling to get an education.”

But the idea that the government earns money off the federal student loan program is controversial. Arne Duncan, the Secretary of Education, refuted the idea in 2013, telling reporters, “It’s actually neither accurate nor fair to characterize the student loan program as making a profit,” according to a Detroit Free Press report at the time.

So why the difference of opinion? It all comes down to a question of accounting. Last year, the Congressional Budget Office predicted that the student loan program would generate $135 billion in profits for the government from 2015 to 2024 or cost the government $88 billion, depending on which accounting method you use.

The method that shows a profit, which the government is required to use to account for its loans, only considers how much goes out in principal loan amount, how much the borrower pays in interest, any fees collected by the government and any amounts not paid by a borrower. Critics say that method doesn’t account for the risk that the budget scorekeepers’ estimates could be wrong because of factors like an unexpected rise in loan defaults or a weaker economy.

Trump didn’t specifically address how he’d curb government profits off the student loan program as president, instead noting “we’re going to restructure it.” Perhaps he thinks he can just change the accounting.
