President Donald Trump's approval rating is the highest it's ever been.

• President Donald Trump's approval rating is at an all-time high of 45% in the Gallup weekly tracking poll.
• And his disapproval rating has hit a near-low of 50%.
• His current approval rating at his point in his presidency lines up with the ratings of other presidents at similar points in their first terms.
• His new spike in approval could take a hit due to the backlash against the administration's controversial policy that has led to separating families at the border.

President Donald Trump's approval rating has reached an all-time high of 45% in a Gallup poll released on Sunday.

Gallup, considered the gold standard of gauging approval ratings, polls a representative sample size of 1,500 Americans by telephone every week, with a margin of error of plus-or-minus 3 percentage points.

Trump's disapproval rating is currently at 50%, the second-lowest point it's been since the very beginning of his first term in January 2017. His disapproval ratings have been as high as 60% in previous months.

Trump's current approval rating 513 days into his presidency is on par with the approval ratings of other presidents at similar points in their first terms. President Barack Obama's approval rating was 45% at day 523 of his presidency, and former President Bill Clinton held 44% approval on day 524.

Data analyst and FiveThirtyEight founder Nate Silver theorized that Trump's sudden spike in approval ratings this week is most likely due to the positive reaction among Republicans to the summit with North Korea's Kim Jong-un.

Silver said that temporary increase would disappear in the coming weeks, as the Trump administration faces mounting backlash from Democrats and Republicans alike over it's controversial "zero-tolerance" policy that has led to the separation of parents and children at the US border.

A Quinnipiac University poll from Monday found that Americans oppose the border separation policy 66% to 27%. The majority of Republicans support it, but by a narrow margin of 55% to 35%.
