He is the first since 1976 to refuse to release his tax returns. He has declined to provide documentation of the “tens of millions” of dollars he claims to have donated to charity. He has yet to release a comprehensive accounting of his health. And, while Wednesday’s letter about Melania Trump’s immigration from her home country offers a few new details, there is no documentation to back up the claims.

At the same time, Trump and his aides are criticizing rival Hillary Clinton as secretive and demanding more information from her about her emails and health. Many Democrats also see Trump’s refusal to release basic information as hypocritical since for years, he was one of the loudest voices demanding that President Obama release his birth certificate to prove he was born in Hawaii and qualified to be president. Trump also called on Obama to release his college applications, school transcripts and passport applications.

Trump’s campaign manager, Kellyanne Conway, played down Trump’s need to release health records on MSNBC on Tuesday: “I don’t know why we need such extensive medical reporting when we all have a right to privacy.”
