The number of Americans who approve of President Donald Trump dropped by 3 percentage points to the lowest level of the year following the release of a special counsel report detailing Russian interference in the last US presidential election, according to an exclusive Reuters/Ipsos public opinion poll. The poll, conducted Thursday afternoon to Friday morning, is the first national survey to measure the response from the American public after the US Justice Department released Special Counsel Robert Mueller’s 448-page report that recounted numerous occasions in which Trump may have interfered with the investigation.According to the poll, 37 percent of adults in the United States approved of Trump’s performance in office, down from 40 percent in a similar poll conducted on April 15 and matching the lowest level of the year. That is also down from 43 percent in a poll conducted shortly after US Attorney General William Barr circulated a summary of the report in March.In his report, Mueller said his investigation did not establish that the Trump campaign had coordinated with Russians. However, investigators did find “multiple acts by the President that were capable of exerting undue influence over law enforcement investigations.” While Mueller ultimately decided not to charge Trump with a crime, he also said that the investigation did not exonerate the president, either.The Reuters/Ipsos poll was conducted online in English throughout the United States. It gathered responses from 1,005 adults, including 924 who were familiar with the Mueller report. It has a credibility interval, a measure of precision, of 4 percentage points. Sharp SplitThe poll found that 50 percent of Americans agreed that “Trump or someone from his campaign worked with Russia to influence the 2016 election,” and 58 percent agreed that the president “tried to stop investigations into Russian influence on his administration.”Forty percent said they thought Trump should be impeached, while 42 percent said he should not.The poll responses were sharply split along party lines, with Democrats much more critical of Trump than his fellow Republicans.
