Monmouth's polling director noted the end of the tax season in highlighting the poll's findings, which he said were not particularly good for Trump.

“The president’s job rating doesn’t see huge swings, so we tend to focus on small movements. The current reading comes at the end of tax return season and while official Washington eagerly awaits the Mueller report. Neither subject is particularly good for Trump,” said Patrick Murray, director of the independent Monmouth University Polling Institute, in a statement.

The poll's results were based on interviews from April 11 to April 15 with 801 adults in the U.S. The poll has a margin of error of 3.5 percentage points.
