A majority of Iowa voters believe the special counsel investigation into Russian interference in the 2016 presidential election should be released in full to the public. But Iowans are more divided on whether they believe President Donald Trump has been truthful when talking about the investigation and whether they think the report has cleared the president of all wrongdoing.All of this is according to a new poll of Iowa voters, conducted by the liberal-leaning Public Policy Polling.A majority of Iowa voters — 53 percent — said special counsel Robert Mueller’s full report should be released to the public, while 38 percent said the full report should not be released publicly.
