CBS News reports it is the first time this many Americans have felt that way since it began polling on the topic.
Fifty percent of Americans who responded to the survey conducted by CBS News said they now think the Russia investigation is justified, with 45 percent saying they think it is politically motivated.
Although the numbers of those who feel the Mueller probe is justified are increasing, Democrats are fueling the surge.
Eighty-three percent of Republican respondents still say the Russia investigation is politically motivated, the same number as said that in November.
