An anonymous reader quotes a report from The Hill: Special counsel Robert Mueller's team has interviewed at least one Facebook employee tasked with helping the Trump campaign's digital operations during the 2016 campaign, Wired reported on Friday. The report, which cited a source familiar with the matter, does not say when the employee was questioned nor does it detail the focus of the interview. Mueller's team has been investigating for months any collusion between Trump campaign associates and Russia. During the election, Facebook deployed employees to embed with the Trump campaign to assist its digital operations. The company also worked with Hillary Clinton's campaign team but did not have employees embedded with them. The company has also been scrutinized by Congress for selling more than 3,000 ads to the Internet Research Agency, a Russian "troll farm" alleged to have carried out misinformation operations online during the campaign.
