Meanwhile, opposition to impeachment dipped 3 points to 42 percent, while 11 percent of those polled in the new survey said they weren't sure or didn't know.

The number of independents who back impeachment doubled to 41 percent.

Trump does not explicitly mention a quid pro quo with Zelensky in the White House memo, though he does segue from a discussion of military assistance to the potential Biden probe. 

The Hill-HarrisX survey surveyed among 1,001 voters and the margin of error was 3.1 percentage points.
