Republican Rep. Jason Chaffetz on Wednesday called on Donald Trump to “open up your kimono” and release his tax returns.

“If you're going to run and try to become the president of the United States, you're going to have to open up your kimono and show everything, your tax returns, your medical records,” the Utah lawmaker said to CNN.


“You're just going to have to do that; it's too important. So both candidates, Donald Trump and Hillary Clinton, should show both their medical records and tax returns, absolutely.”

Clinton released her 2015 tax returns earlier in August , while Trump has declined to do so, citing ongoing audits for multiple years of filing.

Chaffetz echoed a call for both candidates to also release their health records. Earlier Wednesday, retired neurosurgeon Ben Carson, a former GOP presidential candidate, said both candidates need to “disclose their medical history … particularly if they’re elderly.” (Clinton is 68, Trump is 70.)

Trump’s son Eric Trump had earlier rebuffed calls for the Republican nominee to release his tax returns, saying it would be “foolish” to do so.

"His tax return, did you see the Twitter picture, it's 5 feet tall," he said. "You would have a bunch of people who know nothing about taxes trying to look through and trying to come up with assumptions they know nothing about.”
