TRENTON --Anyone worried that Republican Gov. Chris Christie was being held hostage by Donald Trump as he stood, seemingly shell-shocked, behind the GOP presidential front-runner at a Super Tuesday news conference can rest easy.
"No, I wasn't being held hostage. No, I wasn't sitting up there thinking, 'Oh, my God, what have I done?'" Christie said Thursday back home in New Jersey. "I don't know what I was supposed to be doing. All these armchair psychiatrists should give it a break."
He said his face was stoic because he was merely listening as Trump spoke.
"I stood where they asked me to stand. What do I care? Do you think I really care? ... I really don't," he said. "Next week there will be an Internet freakout about something else."
Christie also said that he won't heed calls from a handful of newspapers to resign and will continue helping Trump's campaign. His defense of endorsing the billionaire developer came as two former Republican presidential nominees - most recently Mitt Romney on Thursday - and 70 national security experts warned that Trump was unfit to be commander in chief.
He spoke Thursday at a news conference in Trenton that was part campaign debriefing, part attempt to refocus on priorities in the state. But he opened the floor up to questions after talking about the state budget, and reporters had a lot of them.
Christie, who ended his own Republican presidential campaign last month, said he will continue helping Trump's campaign but doesn't have any more appearances scheduled. Christie added that his 30th wedding anniversary is next week, but he is otherwise focused on state priorities, including a budget due in June.
Seven New Jersey newspapers have called on Christie to resign. The Star-Ledger, which endorsed Christie in his 2013 re-election campaign, said he has since made it clear that governing the state is a "distant second priority" that comes behind his personal ambition. Six newspapers published by Gannett also called for his resignation.
Christie said he isn't surprised by the newspapers' stance because they haven't supported him in the past.
Defending his endorsement, Christie said he believes Trump would make the best president out of the remaining candidates and has the best chance to defeat Democrat Hillary Clinton in the general election.
Christie noted that despite jokes from online commenters, he wasn't forced into giving any coerced statements on Trump's behalf Tuesday night.
"This is part of the hysteria of the people who opposed my Trump endorsement," Christie said.
Christie said he plans to finish out the nearly two years left in his term and then go into the private sector.
He did shoot one question down Thursday. When a reporter asked if he would resign if he were Trump's pick for vice president, he replied, "Next!"
