A new poll shows President Donald Trump’s approval rating has fallen to its lowest level since his inauguration.

The poll from Public Policy Polling, which was conducted for the liberal group End Citizens United, found Trump’s approval seriously underwater, with only 39 percent approving of his job performance and 56 percent opposed.

The results were shared exclusively with CQ Roll Call ahead of their public release.

The survey was conducted quickly, last Thursday and Friday, after the unexpected announcement that Trump had fired FBI Director James B. Comey.

Of the 698 respondents in the automated telephone survey, 51 percent opposed Trump’s decision to terminate Comey. It is the lowest Trump approval that PPP has found since January 20.
