The survey, by TechnoMetrica Institute of Policy and Politics, found 75% of respondents who follow the story think Clinton and her campaign advisers should be investigated for her role in so-called Russiagate, according to several news reports.
Among them, 66% are Democrats – a 20-point rise from last October when the same question was asked.
About the same percentage of independent voters agreed that Clinton should be probed, and 91% of Republicans said the same.
