They're no one's business.
No.
Same place as everyone else's - on file at the colleges he attended.
Actually, we do not know. While Mr. Trump has made national news for demanding that President Obama release his college transcripts, Mr. Trump has refused all media requests to release his own. All we can confirm is that he graduated from the Wharton School at the University of Pennsylvania with a Bachelor's Degree in 1968. But how he did, or what his academic achievements were, has never been revealed. It should be noted that college transcripts are confidential and protected by federal law: neither Mr. Trump nor Mr. Obama is under any obligation to release the information these transcripts contain, and failure to release the information does not mean the person has something to hide.
If you are referring to college transcripts, yes there are, but he has chosen not to make them public; it should be noted that he is not the only president to have made the choice to keep his college records private. If you are referring to printed transcripts of news programs he was on, these are available from the individual networks on which he appeared.
No, he didn't. They were leaked by the press but he never authorized their release.
