"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 BarrBill BarrWe haven't seen how low it can go Trump lashes out at Toomey, Romney after Roger Stone clemency criticism GOP senator says Trump commuting Stone was a 'mistake' 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.
