The figures, coming in almost six months into Trump's term in office, present a downturn for the president, whose approval ratings stood at 42 percent in April.
Trump tweeted about the poll on Sunday, saying "even though almost 40% is not bad...[ABC/Washington Post poll] was just about the most inaccurate poll around election time!"
Asked about Trump's performance as president, half of the respondents answered that he is doing a worse job than previous presidents. Also, 55 percent said that he is not making significant progress toward his goals.
A majority of respondents (60 percent) said that they believe Russia had tried to influence the 2016 U.S. election. Of those, 44 percent think Trump benefited from it and 41 percent believe that members of Trump's campaign helped these Russian efforts. Sixty-three percent of respondents said that the meeting Jared Kushner, Donald Trump Jr. and Paul Manafort held with a Russian lawyer last year was inappropriate.
Just under half of respondents (48 percent) said that America's leadership in the world has gotten weaker under Trump, while only 34 percent answered that they trust the president to negotiate on the United States' behalf with other world leaders to a good or great deal. Those who placed their trust in Trump's ability to negotiate on the U.S.' behalf with Russian President Vladimir Putin to the same degree stood at 32 percent.
The poll was conducted from July 10 to July 13 and was comprised of 1,001 adults. The margin of error was +/- 3.5 percentage points.
