RNA - The Hill-HarrisX survey released on Thursday found 67 percent of Democratic voters support impeachment proceedings against Trump, marking a four-point drop from an identical poll conducted in May.
The poll comes just a week after special counsel Robert Mueller’s public testimony before two congressional House committees, where the special counsel largely stuck to the contents of his 400-plus page report on Russian interference in the 2016 election.
The special counsel said in his report that he didn’t find sufficient evidence of collusion between Russia and the Trump campaign. He also didn't conclusively determine whether the president committed obstruction of justice, even though he outlined nearly a dozen instances involving Trump.
Trump and his allies celebrated the testimony as a victory and declared that the “phony cloud” cast by the investigation had been lifted.
But a number of House Democrats have come out in favor of opening an impeachment inquiry into Trump since last week, citing Mueller’s testimony.
Democratic leadership has long called for restraint on impeachment.
A day after Mueller's testimony, Speaker Nancy Pelosi (D-Calif.) said she would only move forward on impeachment efforts if the caucus had a strong hand.
"My position has always been [that] whatever decision we make in that regard would have to be done with our strongest possible hand, and we still have some outstanding matters in the courts," Pelosi said during a news conference.
HarrisX conducted the survey of 1,000 registered voters between July 27 and July 28. The margin of error for the sample is plus or minus 3.1 percentage points.
