The FBI and the New York attorney general were looking into a spate of mysterious robocalls urging people to stay home on Election Day as the nation remains on high alert to ensure voting is not compromised.
"There's a little bit of confusion about this one across the industry," said Giulia Porter, vice president at RoboKiller, a company that fights telemarketers and robocalls and has been tracking the campaign.
Audio of the calls, which RoboKiller shared with Reuters, features a synthetic female voice saying: "Hello. This is just a test call. Time to stay home. Stay safe and stay home." Porter said the call had been placed millions of times in the past 11 months or so but had on Tuesday shot up to No. 5 or No. 6 in the list of top spam calls.
