Alabama Attorney General Steve Marshall said Thursday that his office is exploring whether disinformation tactics deployed against Republican Roy Moore during last year’s special election violated state campaign laws and said he was worried that the operation could have affected the closely fought Senate race…

Marshall said in the interview that the rapidly changing nature of campaigning on social media has made it difficult for authorities to know how to address disinformation tactics in elections.

“Technology has put us in a difficult position in many respects in terms of the applicability of our current laws,” Marshall said.
