The University of Delaware is keeping a trove of documents and information about former Vice President Joe Biden's Senate career under wraps under a policy that will shield it throughout his presidential campaign and potentially beyond.

Biden donated a trove of his Senate records to the University of Delaware eight years ago.

Had he retired and ended his career, scholars might now be sifting through them. But the school appears to have modified the terms of release this year, as Biden jumped into the presidential race.

Under an initial agreement, the records were to remain sealed 'for two years after Biden retires from public office.'

Now, the Washington Post has reported, the school says the record will be sealed until Biden “retires from public life” or after Dec. 31, 2019.

'The entire collection is unavailable,” spokeswoman Andrea Boyle Tippett,a spokeswoman for the school, Biden's alma mater, told the paper. “Its contents will become available, as the website indicates, when Mr. Biden retires from public life.”

She also pointed to his current campaign, where he is the front-runner. “As he is currently running for office, he is in public life.'

The effect of the policy makes it harder not only for scholars to begin research, but for the press to explore Biden's past work with a range of Senate figures – including segregationists. Biden brought up his past work even with figures he disagreed with, at a New York fundraiser.

Sen. Kamala Harris of California blasted him at the first Democratic debate for his statements and his past views on school busing.

With a collection holding 1,875 boxes of material plus digital files, the documents could hold additional material that could cause Biden political headaches.
