Arnold Schwarzenegger's feud with Donald Trump is showing no signs of terminating.
After Schwarzenegger announced he won't be back for a second season of Celebrity Appearance, Trump - the show's former host - took to Twitter to bag on the action hero.
"Arnold Schwarzenegger isn't voluntarily leaving the Apprentice, he was fired by his bad (pathetic) ratings, not by me. Sad end to great show," the President wrote.
Schwarzenegger, also a big Twitter fan, responded quickly, writing: "You should think about hiring a new joke writer and a fact checker."
Trump has regularly used his Twitter account to attack Schwarzenegger, who took over Celebrity Apprentice when Trump turned to politics.
Schwarzenegger said he had a good time making the show, but it had too much "baggage" and blamed Trump's relentless attacks on the show's poor ratings.
"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."
In February, he offered to switch places with Trump.
"You take over TV because you're such an expert on ratings and I take over your job and then people can finally sleep comfortably again."
Trump's tweet at Arnie came after he accused former President Barack Obama of wiretapping his phone, without providing any evidence.
