"When you're let out ... there are restrictions placed on you for you to stay out. And one of the restrictions that was placed on him was no contact or intimidation of potential witnesses," the former prosecutor said.
Christie lobbied harder than anyone to become Trump’s vice-presidential pick, but he was passed over in a way that seemed to surprise him. Then Christie took over Trump’s 2016 transition team, before being quickly pushed aside. Trump declined on multiple occasions to make him attorney general, the cabinet job Christie was most suited for, leading Christie to explain in early 2019, “He hasn’t offered me anything that I really wanted to do.”
It was at this point that the cracks in their alliance began to form, and they became chasms after Jan. 6, 2021. Christie has even blamed Trump for giving him a coronavirus infection that landed him in intensive care in late 2020. He said Trump never called to check on him.

Correction, he did call but only to make sure that Christie wouldn’t tell people that he was the one that infected him.
