As Robert Mueller’s investigation into Russian interference in the 2016 election inches closer to the President, approval of Donald Trump’s handling of the investigation has fallen, matching its all-time low in CNN polling. The findings, from a new CNN poll conducted by SSRS, come as half of Americans say they think it is likely that the Mueller investigation will implicate the president in wrongdoing.

In the new poll, Trump’s approval rating for handling the Russia investigation dips to 29%, matching a low previously hit in June of this year.
