Americans are split over whether House Democrats should continue to investigate President Trump after special counsel Robert S. Mueller III made no determination about whether he attempted to obstruct justice during the inquiry into Russian interference in the 2016 election, a Washington Post-Schar School poll finds.

The division marks a clear break from public support for Russia-related investigations at the start of the year, when an overall majority supported House Democrats’ efforts to examine whether Trump’s subordinates conspired with Russia as well as Trump’s relationship with Russian President Vladimir Putin.

Six House panels are digging into aspects of Trump’s campaign, his finances and his efforts to discredit Mueller’s inquiry as a “witch hunt,” while they wrestle with Attorney General William P. Barr for access to Mueller’s full report and the underlying evidence that informed his conclusions. Mueller did not find that Trump or his campaign conspired with Russia in 2016.
