As lawmakers on Capitol Hill turn up the heat on Facebook, another social network has also offered to cooperate with the Senate Intelligence Committee’s investigation into Russian interference in the election: Twitter has confirmed that it will speak with senators next week regarding the spread of propaganda on its platform, as well as the huge number of fake and foreign bot accounts that proliferated in 2016. Investigators are also reportedly looking at how Russia-linked accounts shared stories and memes that were picked up by conservative news sites.

While Twitter is smaller than Facebook, it has an outsize impact in media circles, and there are effectively no checks preventing misleading information from quickly going viral. It’s a dynamic that Russia appears to have seized on during the election: multiple outlets have noted how the Kremlin employed a cyber-army of bloggers and automated Twitter accounts run out of troll factories overseas to propagate pro-Trump and anti-Clinton messages. With no simple way to verify information and no disclosure law for partisan social-media posts, the system was ripe for exploitation.

Twitter says that it is eager to work with governments to help solve the problem. “We are cooperating with the Senate Select Committee on Intelligence in its inquiry into the 2016 election and will meet with committee staff next week,” a spokesperson told Wired. “Twitter deeply respects the integrity of the election process, a cornerstone of all democracies, and will continue to strengthen our platform against bots and other forms of manipulation that violate our Terms of Service.”

It’s unclear what, specifically, Twitter will present to the Senate Intelligence Committee; likely, the company will discuss the deluge of bots that have long plagued its platform. Facebook is often singled out, in the wake of the election, as having been a hotbed of misleading-news stories and outright hoaxes, but Twitter has its own insidious fake-news problem. Users can buy bot accounts for just a few hundred dollars, using them to boost their following counts, or to send automated messages and share fake-news stories. One estimate suggests that 59 percent of Donald Trump‘s followers are fake accounts or bots, while 66 percent of Hillary Clinton’s are fake, according to The Washington Post. Wired reports that the group Securing Democracy is monitoring 600 Twitter accounts linked to Russian operatives, which includes bot accounts. (Twitter has said that it is “working hard to detect spammy behaviors” by identifying bots and hiding fake accounts.)

For years, big tech companies have managed to stay off of Congress’s radar, buoyed by consumer goodwill and trust. Now, that seems to be changing, as the federal government is examining the role companies like Facebook and Twitter had in swaying the 2016 election, and how they may have been weaponized. Democrats are demanding the F.E.C. require more transparency from social-media platforms like Facebook, asking that they take steps to prevent being manipulated by foreign agents in the future. And the backlash is building quickly. “They have a responsibility. And if they say, ‘Well there’s no ways to do it other than we’re going to have a human being read every message,’ I’m sorry, you’re going to have to do that,” former New York mayor and billionaire political donor Michael Bloomberg told Axios on Wednesday, expressing an increasingly common complaint. “That's their problem. It’s not society’s problem.”
