(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 committee hired an online intelligence firm to review data on Russian social media accounts that posed as American accounts. The data, much of which has not yet been made public, was provided to lawmakers by Facebook, Twitter and Google, which owns YouTube. 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. The firm advised lawmakers that there are likely more Russian accounts that the social media companies failed to identify, according to person familiar with the report.
