A majority of registered voters back Attorney General William Barr’s order for a federal prosecutor to look at the origins of the federal Russia investigation, a new poll says.

According to a Hill-HarrisX survey conducted from May 17-18, 62% of registered voters support Barr recently assigning U.S. Attorney John Durham in Connecticut to head an investigation examining the genesis of the federal Russia investigation.

Seventy-four percent of Republicans said they supported the inquiry, while 48% of Democrats said they opposed it.

The inquiry is the third known federal probe trying to uncover information about the start of the FBI’s counterintelligence investigation into the Trump campaign’s ties to Russia. This later turned into special counsel Robert Mueller’s federal Russia investigation.

Barr questioned whether the Justice Department acted appropriately during the federal Russia investigation when he raised questions about whether Trump campaign members were spied on by the FBI last month.

“I think spying did occur,” Barr said before the Senate Appropriations Committee. “The question is whether it was adequately predicated. And I’m not suggesting that it wasn’t adequately predicated. But I need to explore that.”

The survey has a sample size of 1,030 registered voters with a margin of error of 3.1 percentage points.
