US imposes sanctions on Russian and Iranian groups over disinformation targeting American voters

The U.S. has imposed sanctions on two groups linked to Russian and Iranian disinformation campaigns targeting this year's election. Treasury officials announced the actions Tuesday, saying the two groups sought to spread false claims designed to stoke political tension and undermine the candidates ahead of November's vote. Officials say the Russian organization worked with Russian military intelligence and used artificial intelligence to create fake videos about American candidates. The Iranian group is accused of working at the direction of Iran's military to spread disinformation aimed at inciting voters. Both countries have rejected accusations that they sought to meddle with the election.
