In the University's latest survey, 43 percent asked said they approve of the overall job Trump is doing as the President, while 32 percent said they approve of the job being done by Congress.
Though by a slightly lower margin, more people also disapprove of the job Congress is doing compared to Trump.
More than half disapproved for both, 55 percent for Congress and 51 percent for Trump.
The poll was conducted by interviewing 808 adults aged 18 and older between April 30 and May 4 over telephone.
It was carried out by the Monmouth University Polling Institute in West Long
Branch, New Jersey and has a margin of error of plus or minus 3.5 percent.
As well as giving an overarching view on the work carried out by Trump, respondents were also asked specifically about his handling of the coronavirus pandemic.
On this, the amount who believed he has done a bad job tipped beyond half, reaching 51 percent.
This is up from 45 percent in March, according to a previous Monmouth University poll.
Of those polled, 42 percent said Trump was doing a good job in response to the outbreak of coronavirus, down from 50 percent in March.
Patrick Murray, director of the independent Monmouth University Polling Institute, said: "The month to month shifts are well within the poll's margin of error, but the overall trendline suggests that the public is growing less satisfied with Trump's response to the pandemic."
For Congress, 38 percent said it is doing a good job in response to coronavirus, while 47 per cent said it was doing badly.
This also showed a decline in perception of its response. In March, 42 per cent rated it as doing a good job and 37 per cent responded bad.
The president and Congress have clashed at points throughout the coronavirus pandemic on decisions of how to deal with the implications of the outbreak.
Congress recently turned down an offer from the Trump administration for rapid coronavirus testing on Capitol Hill.
A joint statement from Senate Majority Leader Mitch McConnell and House Speaker Nancy Pelosi declined the offer, calling for such resources to be directed to "front-line facilities." Trump questioned this decision, suggesting that by turning the offer down they were suggesting they were not "essential."
Last month, Trump also threatened to adjourn Congress in order to push through nominees which would usually require Senate confirmation, stating a need for them to be put into positions due to the pandemic.
The Senate has since returned to business, with members attending Capitol Hill on Monday.
However, the House of Representatives have stayed away, due to safety concerns, despite Republican calls to get back to business.
