Trump campaign submits over 20,000 pages of documents in Russia probe

The documents were handed over in compliance with a Senate panel investigation.

The Trump campaign sent more than 20,000 pages of documents to the committee last Wednesday, the deadline to submit documents, and Manafort handed over about 400 pages, including his foreign-advocacy paperwork, on the same day, according to the spokesperson.

Trump Jr. submitted about 250 pages on Friday, the spokesperson said.

Fusion GPS — the opposition research firm linked to a controversial dossier containing numerous allegations about Trump and his campaign — and its owner, Glenn Simpson, have yet to turn over documents, the spokesman said.

The panel said it hopes to have staff-transcribed interviews with all three men in a closed session before they testify in a public hearing but that negotiations with them are ongoing.
