Once the news broke that action movie star Arnold Schwarzenegger was hired as the replacement host for "The New Celebrity Apprentice," it was only a matter of time before Donald Trump went on the attack. In the last 48 hours, the two men have gone back and forth in a word of words, with the star of "The Terminator" firing the most recent shot.

Arnold on Trump

Arnold Schwarzenegger has been one of the most well-known Republicans in Hollywood, and served as the governor of California almost a decade ago. Despite being a conservative, Schwarzenegger has broken with the Republican Party on key issues, including Climate Change and support for the LGBT community.

Earlier on in the presidential race, Schwarzenegger confirmed that he would support Donald Trump in the general election after his first choice, Ohio Gov. John Kasich, dropped out. In recent days, the former governor's feud with Trump has only escalated, prompting Schwarzenegger to troll the new commander in chief in a February 3 Twitter post.

On Thursday morning during the annual National Prayer Breakfast, Donald Trump poked fun at Arnold Schwarzenegger for the low ratings on "The New Celebrity Apprentice," asking those in attendance to pray for the movie star. In response, Schwarzenegger released a video statement where he offered to switch jobs with Trump, where the billionaire real estate mogul could return to reality TV, and he could move into the White House.

Shorty after 6 a.m. on Friday morning, Donald Trump lashed out against the former governor in a post on Twitter. "Yes, Arnold Schwarzenegger did a really bad job as Governor of California and even worse on the Apprentice," Trump wrote, while mockingly adding, "but at least he tried hard!" Hours later, the former "Predator" star used his own Twitter account to link back to a 2006 article when Schwarzenegger was still the governor, showing that he released his Tax returns, a topic that is still a mystery to Trump since the president keeps his financial records private.
