Arnold Schwarzenegger is turning the table on Donald Trump by taking to social media to criticise the president's own approval ratings.
Schwarzenegger posted a video to Twitter referencing a new Gallup poll that showed Trump's approval rating at 39 percent, down 6 points from a week earlier.
Schwarzenegger told Trump: "The ratings are in and you got swamped."
The action star and former California governor replaced Trump as the host of Celebrity Apprentice, and Trump repeatedly mocked him for poor television ratings.
Schwarzenegger recently said he wouldn't return to the show.
Schwarzenegger also criticised Trump's proposed budget cuts, including to after-school programs.
He invited Trump to visit a Washington, DC, middle school with him to see "fantastic work" being done for children.
Schwarzenegger didn't support Trump during his presidential run.
Schwarzenegger's video is the latest blow in an ongoing feud between the actor and the US president. Schwarzenegger previously joked he would "smash [Trump's] face into the table" during a meeting.
When Schwarzenegger announced he was leaving Celebrity Apprentice, he cited Trump as the reason for the show's poor ratings, telling Empire magazine "when people found out that Trump was still involved as executive producer and was still receiving money from the show, then half the people [started] boycotting it."
Trump then said Schwarzenegger was not voluntarily leaving the show, but had rather been "fired by his bad (pathetic) ratings".
Arnold Schwarzenegger isn't voluntarily leaving the Apprentice, he was fired by his bad (pathetic) ratings, not by me. Sad end to great show— Donald J. Trump (@realDonaldTrump) March 4, 2017
Celebrity Apprentice wrapped up its 15th season last month, averaging fewer than 5 million viewers per episode.
