The latest poll from Quinnipiac University has seen President Donald Trump's approval rating drop to a new low.
The survey, carried out among 1,056 voters between March 16 and March 21, also showed Trump losing ground among his core base, according to Quinnipiac.
Trump's approval rating among Republicans was 81 percent, down from 91 percent in a March 7 Quinnipiac poll. Among men, who approved of Trump's performance in the previous poll, 52 percent said they disapproved of the job Trump was doing, compared to 43 percent who approved.
Among white voters, 50 percent disapproved, while 44 percent approved.

"Although taking a beating, he keeps on tweeting to the point where even his fiercely loyal base appears to be eroding," said Tim Malloy, deputy director of the poll.
"Most alarming for President Donald Trump, the demographic underpinnings of his support, Republicans, white voters, especially men and those without a college degree, are starting to have doubts," he added.
Overall, this meant Trump's approval rating fell to 37 percent, with 56 percent disapproving.
Voters also seem to be losing confidence in Trump's personal qualities. Of respondents, 60 percent said Trump was not honest, compared to 55 percent in the March 7 survey. And 57 percent said he did not care about average Americans, 55 percent thought he did not have good leadership skills and 66 percent believed he was not level-headed.

When voters were asked about the way Trump was dealing with specific policy areas, the numbers did not improve for the president. The poll found 58 percent of participants disapproved of the way Trump is handling foreign policy, 54 percent disapproved of his approach to the federal budget and 60 percent disapproved of his immigration policies.
On Trump's allegation that former President Barack Obama wiretapped Trump Tower, only 19 percent believed this had happened against 70 percent who did not. Of those polled, 48 percent said Trump believed the allegation he made against Obama via Twitter, while 42 percent stated he did not.
Some blame Trump's use of Twitter for his declining popularity.
"The tweets make it much more difficult for us as we try to build a case against these leakers," Republican Rep. Peter King of New York told the Boston Globe. "We always have to be answering questions about the tweets -- it puts us on defense all the time when we could be building a case for the president."
Trump received similarly low approval ratings in a Gallup poll published March 20. The survey showed him with a 37 percent approval rating.
