New Jersey Gov. Chris Christie was deeply insulted by a voicemail message left from Marco Rubio after he'd dropped his bid for the GOP presidential nomination, according to sources close to the state leader whose Friday endorsement of Donald Trump shook up the party.Christie came out strong against the Florida senator, attacking him before and during a party debate by calling him shallow and scripted,However, Christie lost the Granite State after a pro-Rubio group, Conservative Solutions, released advertising bashing Christie as being President Barack Obama's "favorite Republican" and attacked him for his stances on Common Core and Obamacare.After the spots aired,declared that Rubio's campaign was "running the most traditional negative campaign in New Hampshire," but many pundits said the ads also led to Christie losing in a state where he'd campaigned hard.And after losing the race, the call came from Rubio.In his voicemail, the junior Florida senator sought Christie's support and assured him that he still had a bright future in public service — and Christie didn't appreciate the words, sources close to the governor said.Instead, Christie, 53, took the message to be patronizing and deeply disrespectful, and wanted to know why 44-year-old Rubio would be telling him about his future, and the two politicians never held a direct conversation.But Trump was more persistent, reports The Times. He had been calling Christie frequently once he was no longer a rival for the party crown, and on Thursday, the two met at Trump Tower in New York City with their wives. One day later, Christie was in Texas, endorsing Trump while mocking Rubio.
