Most Americans want a special prosecutor to investigate Russian contact with Trump campaign officials, according to a new poll.

In all, 65 percent of Americans believe an independent special prosecutor is needed to handle the investigation, while only 32 percent believe “Congress is capable of handling the investigation,” according to a CNN/ORC poll released Monday.

The poll’s findings are somewhat partisan, as 82 percent of Democrats favor a special prosecutor, while only 43 percent of Republicans support one. Sixty-seven percent of self-identified independents favor a special prosecutor.

Likewise, 71 percent of Americans find the Trump campaign’s alleged contact with Russian officials very concerning, while only 7 percent of Republicans are very concerned.

Nevertheless, the poll finds President Trump’s approval ratings up 1 percentage point from January to 45 percent. The president’s disapproval rating is at 52 percent, however.

The results of the national poll come days after Trump accused former President Barack Obama of wiretapping him while he was running for the Oval Office last year.

On Sunday, the White House called for an investigation into Obama and his alleged executive overreach.

The CNN/ORC poll surveyed 1,025 adults between March 1 and March 4 and has a margin of error of 3 percentage points.
