Senators from both sides of the aisle told top staffers from Google, Facebook and Twitter during a hearing Tuesday that they are skeptical of the company's massive influence and their ability to police abuse on their platforms after online Russian election meddling last year.

Tech response: The tech giants have presented a mostly united front during the hearing, telling the Senate Judiciary Committee's crime panel that, while the amount of Russian-sponsored ads and content on their platforms during last year's election was relatively small compared to their total user bases, they're committed to making sure it doesn't happen again.

Key quote: "I do not want to suggest in any way that we don't think this is a big deal," said Facebook General Counsel Colin Stretch. "We think this is a huge deal."
