Trump's disapproval rating surges above 50 percent. President Donald Trump became the first president in modern history to have more than half of Americans disapprove of his job performance after only eight days in office, according to a new poll. The Gallup survey has tracked the approval rating of all presidents dating back to the administration of Harry Truman. As of Saturday, Trump's approval rating was at 42 percent, while 51 percent of respondents said they disapproved of his performance as president so far. Trump's rating hovered around an equal 45 percent approval to disapproval in the first few days and began to split on Thursday, the day after he signed an executive order moving forward with his proposed border wall on the U.S. border with Mexico.
