NEW JERSEY (CBS NEWS) -- On Thursday, President Trump will mark six months in office with the lowest approval rating of any president going back 70 years.
A new national poll out Sunday shows just 36 percent of Americans approve of Mr. Trump's job performance so far.
Mr. Trump's disapproval rating has jumped to 58 percent.
Meanwhile, Mr. Trump shrugged off the poor grades with a tweet that read: "The ABC/Washington Post Poll, even though almost 40% is not bad at this time, was just about the most inaccurate poll around election time!"
