Twitter will send its acting general counsel to testify before the House and Senate Intelligence committees in hearings regarding Russian interference in the 2016 presidential election, according to a company spokesperson.

Twitter's Sean Edgett will join Facebook's general counsel, Colin Stretch, who is also set to testify at both hearings on Nov. 1, the social media giant said on Thursday.

Google, which was also invited to the hearing, has not yet commented on if it will send a representative to testify. Lawmakers, however, have said that they expect all three companies to attend.

The top Democrats on the House and Senate Intelligence committees, Rep. Adam Schiff (Calif.) and Sen. Mark Warner (Va.), respectively, have spoken positively about Facebook's improved cooperation with their investigation but have been less favorable to Twitter.

After Twitter briefed both Intelligence committees on its findings in regard to Russian election influence on its platform, Warner blasted the company.

"Their response was frankly inadequate on almost every level," he said. The Virginia Democrat said that Twitter's investigations were focused on accounts that were linked to the ones Facebook released and noted that he wanted more comprehensive information on how Russian actors may have used the platform.

Warner and Schiff say that they plan to use the hearing to get more answers from the companies on the role they may have played in Russian election meddling.
