Edit: Did the legwork for you, and what do you know, of course it's mudbrain nonsense:

"As was reported back in late 2016, the Obama team was transferring the records to Chicago through the National Archives, which legally owns the documents once a president leaves office. Once the documents ultimately reached a warehouse in Chicago, the Obama Foundation was then due to pay the National Archives and Record Administration to digitize the documents. The lengthiness of that process aside, there isn’t the faintest hint of legal violations — nor does the Post’s story suggest as much.

The faintest hint of evidence, of course, is currently surplus to requirements on many portions of the right. Hannity stated conspiratorially that “they shipped 30 million pages of sensitive and possibly classified materials to Chicago,” without noting that the “they” included the National Archives."
