The CBS News poll, released Wednesday, indicates 49 percent of Republicans think it’s not very or not at all likely that Trump associates had improper dealings with Russia. The poll reflects responses gathered after Trump’s former national security adviser Michael Flynn pleaded guilty to lying to the FBI about his contacts with Russia.

Two-thirds of Americans said they believe Flynn’s guilty plea is a “serious matter” for the Trump administration, according to the poll.
