(CNN) The Senate Intelligence Committee has been advised that social media companies might have provided the "bare minimum" amount of data to aid the panel's investigation into Russian meddling in the 2016 presidential election, according to a person familiar with a report commissioned by the committee.

The Senate Intelligence Committee is set to release two reports on Monday detailing the breadth of a Russian social media campaign to sow discord in the United States, a source familiar with the release told CNN.

The reports, both commissioned by the committee, are based on troves of data Facebook, Twitter, and Google handed over to the committee about the Russian campaign to influence the 2016 US presidential election. Much of the data has not previously been disclosed publicly.

The committee hired an online intelligence firm to review data on Russian social media accounts that posed as American accounts.

New Knowledge, one of the firms hired by the committee, tracks online disinformation. In its report to lawmakers, the firm said that the social media companies could have provided more valuable data to the committee and also could have presented it in a more accessible format.
