President Donald Trump's approval rating remains below 40 percent as the White House reels from controversies related to its ties to Russia and the firing of FBI chief James Comey.

The latest Gallup poll shows 38 percent said they approve of the job Trump is doing. Fifty-six percent said they disapproved of the way Trump was handling his job, according to the poll conducted May 8-14.

The president's approval figure is the lowest since the end of March, when those saying they thought the president was doing a good job was also listed as 38 percent.

At the start of May, Trump's approval rating was 40 percent, but the recent allegations regarding the president - including that he asked Comey to not continue an investigation into former national security adviser Michael Flynn - have taken its toll on the White House.

The Gallup results track closely to numbers from fivethirtyeight.com's polling average, which includes Gallup, Rasmussen, Monmouth University, YouGov, Ipsos and more. The president's average approval rating in the compilation is 39.5 percent.

Democrats unpopular, too

While Trump's poll numbers continue to be low, things aren't much better for Democrats.

While Trump's own party - the Republicans - have an approval rating of only 39 percent, that number is basically unchanged since Gallup last asked the question in November 2016.

Democrats, however, have fallen to a 40 percent approval rating from 45 last November.

The latest numbers come from a May 3-7 Gallup poll which asked Americans whether they have a favorable or an unfavorable opinion of each party.

"So far, Trump's unpopularity as president has done little to erode Americans' views of the GOP, perhaps because they were already quite negative. However, Americans are now less positive toward the Democratic Party than they were last fall," Gallup noted.

In November 2016, 83 percent of Democrats had a positive opinion of the Democratic Party; now, 77 percent do. Independents are also slightly less positive toward the Democratic Party, while Republicans' negative views of the opposing party are steady.

Currently, 79 percent of Republicans have a favorable opinion of their party. Thirty-three percent of independents and 9 percent of Democrats rate the Republican Party favorably.
