Since President Donald Trump defeated Hillary Clinton in last year's presidential election, the overwhelming Democratic narrative has been that Trump committed some wrongdoing in his victory.
First, Democrats alleged that Trump and members of his campaign colluded with Russian operatives during the election to undermine Clinton's campaign and win the White House. No concrete evidence to suggest collusion has surfaced. The FBI has only publicly confirmed an intelligence investigation into Trump's campaign.
But in recent weeks, the main narrative has been that Trump committed obstruction of justice when he exercised his constitutional right to fire FBI Director James Comey. Critics argued Comey's dismissal amounted to obstruction because the FBI was in the midst of their investigation into Trump's campaign.
And it appears that narrative is resonating with Americans.
According to a new poll from the Associated Press and the University of Chicago's NORC Center for Public Affairs Research, 61 percent of Americans surveyed believe Trump has tried to impede or obstruct the FBI's investigation into his campaign, while just 37 percent said they believe Trump hasn't tried to impede or obstruct the investigation.
The poll also found there is a growing concern over the possibility that Trump's campaign colluded with Russian operatives during last year's election. When asked, 48 percent said they are extremely or very concerned about the possibility, up from 44 percent in March, while just 30 percent said they aren't very concerned or not concerned at all, down from 36 percent in March.
An overwhelming majority, 52 percent, also said they disapproved of Trump's decision to fire Comey, while 22 percent said they approved of the decision and 24 percent said they were indifferent.
In addition, the poll found that not many Americans believe special prosecutor Robert Mueller will carry out a fair and impartial investigation. Only 26 percent said they were extremely confident in Mueller's ability, while 36 percent each said they were moderately confident or not confident at all.
The survey was conducted between June 8-11 and polled 1,068 respondents, with 46 percent being Democrats, 33 percent being Republican and 21 percent being independents. It has a margin of error of 4.1 percent.
