Most Americans believe that senior Trump officials probably had improper contact with Russia during the 2016 presidential election, according to a new poll conducted by the Pew Research Center.

Fifty-nine percent of Americans believe that Trump's aides probably or definitely had inappropriate ties to Russians. According to Pew, 29 percent of respondents said the campaign officials "probably" did, while 30 percent said they "definitely" did.

The results are skewed along partisan lines. About a quarter of conservatives said that the officials likely had improper contacts, while more than 80 percent of liberals did.
