Facebook and Twitter will be represented by their general counsels, while Google will send its director of law enforcement and information security.

On Wednesday, the general counsels for all three companies are scheduled to testify in back-to-back hearings before the Senate and House Intelligence committees.

They will brief lawmakers on Russian efforts to use their platforms to influence the 2016 presidential election.

Graham told Politico earlier this week that he had been asking the tech companies to attend the hearing.
