Pollster Mallory Newall said in an interview that aired Tuesday on Hill.TV's "What America's Thinking" that support for President TrumpDonald John TrumpPapadopoulos on AG's new powers: 'Trump is now on the offense' Pelosi uses Trump to her advantage Mike Pence delivers West Point commencement address MORE among his base could be softening amid the release of special counsel Robert MuellerRobert (Bob) Swan MuellerThe Hill's 12:30 Report: Trump orders more troops to Mideast amid Iran tensions Trump: Democrats just want Mueller to testify for a 'do-over' Graham: Mueller investigation a 'political rectal exam' MORE's report on Russia's election meddling in 2016. 

"There has been a little bit of softening in the president's standing," Newall, research director at Ipsos Public Affairs, told host Jamal Simmons on Monday. 

"[It's] not necessarily that those who support him have moved away from him, it's just that they're a little more unsure than they were before," she continued. 

Newall went on to say that the number of people who are for impeachment and those who are against it are about even now since Attorney General William BarrWilliam Pelham BarrPapadopoulos on AG's new powers: 'Trump is now on the offense' House Democrats must insist that Robert Mueller testifies publicly Why Mueller may be fighting a public hearing on Capitol Hill MORE released his four-page summary of the Mueller report late last month.

Newall was referring to a Reuters/Ipsos poll released last week that showed 40 percent of respondents believe Trump should be impeached, while 42 percent say he should not. 

"The number of people saying that he shouldn't [be impeached] has decreased, and it's basically an even split now," she said. 

The Reuters/Ipsos poll also showed a 3-point drop in Trump's approval rating after the report's release. 

Meanwhile, the Politico/Morning Consult survey out on Tuesday found that just 39 percent of voters polled said they approved of Trump's performance, marking his lowest approval rating since August 2017.
