President Trump's job approval sank toward a two-year low on Wednesday, according to a survey from the right-leaning polling firm Rasmussen.

The poll released Wednesday shows 42 percent of likely U.S. voters approve of Trump's job performance, while 57 percent disapprove.

That's a net 4-point drop in approval since Friday when 46 percent of respondents said that they approved of the president, while 53 percent said they disapproved. The drop marks the lowest level for the president since Jan. 22, 2018, when Trump's approval rating was underwater, at 42 percent to 56 percent.

The latest figures also show that 30 percent of likely voters "strongly approve" of Trump's work in office while 47 percent "strongly disapprove," giving him a net negative approval index rating of 17 percent — the biggest margin since January 2019, according to Rasmussen's figures.

The poll comes as the president faces backlash, including heavy criticism from some conservative corners, over his tweets in recent days raising a conspiracy theory about the death of an aide to former Rep. Joe Scarborough (R-Fla.).

Trump has also locked horns with top Democratic leaders recently, including throwing a number of barbs at former Vice President Joe Biden, his presumptive Democratic rival in November, and feuding with Speaker Nancy Pelosi (D-Calif.) amid debate over the next phase of coronavirus relief.

Rasmussen's tracking poll was conducted among 1,500 likely voters via telephone and online with an overall margin of error of +/- 2.5 percentage points.
