The number of Americans who approve of President Trump dropped 3 percentage points — to the lowest level of the year — following the release of a special counsel report detailing Russian interference in the election, a Reuters/Ipsos poll said Friday.

The poll, conducted Thursday afternoon to Friday morning, was the first to measure America’s response after the Justice Department released special counsel Robert Mueller’s 448-page report, which detailed a number of times that the president may have interfered with the investigation.

According to the poll, 37% of adults approved of Trump’s performance in office, down from 40% in a similar poll conducted on April 15 and matching the lowest level of the year.

That is also down from 43% in a poll conducted shortly after Attorney General William Barr circulated a summary of the report in March that was favorable to the president.

In his report, Mueller said his investigation did not establish that the Trump campaign had coordinated with Russians.

But 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 poll found that 50% of Americans agreed that “Trump or someone from his campaign worked with Russia to influence the 2016 election,” and 58% 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% said he should not.

The poll responses were sharply split along party lines, with Democrats much more critical of Trump than his fellow Republicans.

Among respondents who said they were familiar with the Mueller report, 70% said the report had not changed their view of Trump or Russia’s involvement in the presidential race.

Only 15% said they had learned something that changed their view of Trump or the Russia investigation, and a majority of those respondents said they were now more likely to believe that “Trump or someone close to him broke the law.”
