Arnold Schwarzenegger is not backing down after President Donald Trump again insulted the "New Celebrity Apprentice" host and former California governor in another early morning tweet on Friday.
After Trump tweeted that Schwarzenegger "did a really bad job as Governor of California and even worse on the Apprentice," Schwarzenegger tweeted back at Trump with a link to a news story from 2006 detailing the release of Schwarzenegger's tax returns as part of his gubernatorial re-election bid.
Sharing the link was a direct dig at the new president, who has been dogged by criticism of his decision to withhold his tax returns and details of his financial obligations since he began his bid for the Presidency. He was the only major party nominee for president in over 40 years who has refused to make such disclosures.

There have been calls online for protests to take place on April 15, Tax Day in the U.S., in an effort to get Trump to release the documents.
Schwarzenegger and Trump have been trading barbs online for weeks, with the president taking time off from running the country to criticize the lackluster ratings of NBC's "Celebrity Apprentice" with the former "Terminator" star as host.
"When I ran for president, I had to leave the show. They hired a big, big movie star Arnold Schwarzenegger to take my place and we know how that turned out. The ratings went right down the tubes," Trump said Thursday.
Schwarzenegger responded fast, posting a video in which he asked to switch gigs.
"Hey Donald, I have a great idea. Why don't we switch jobs? You take over TV, because you're such an expert in ratings, and I take over your job and then people can finally sleep comfortably again," Schwarzenegger said.
