Posters on 4chan, the anonymous message board famous as a gathering spot for trolls, shared the phone number of Iowa's Democratic caucus results line Monday evening and encouraged readers to "clog the lines," NBC News reports.
Why it matters: Technical problems with a results-tallying app led many Iowa precincts to try to report numbers by phone. The lines were already overloaded, but it now appears that malicious mischief might also have played a role.
One Democratic party official who helped man the phone line told colleagues he had received multiple calls to the line from Trump supporters who expressed "displeasure," Bloomberg reported Wednesday.
