"We have tried to get ahold of him. I think he's taking a few days away from all the grind," Rubio told CNN on Sunday. "And I understand that. I know we spoke to his staff. So, we're trying to set up a time to talk."
After that night, the Rubio campaign was dogged by so called "Rubio-bots," protesters sent by Democratic groups to rub salt in the wounds. The robot fiasco could have contributed to Rubio's poor performance in New Hampshire.
"I'm disappointed with tonight," Rubio told supporters in a speech after the New Hampshire primary. "But I want you to understand something: Our disappointment tonight is not on you.
"It's on me. I did not -- I did not do well [in the debate] on Saturday night. So listen to this: That will never happen again."
But now with Christie out of the presidential race, Rubio seems to want to mend bridges.
"I have no animus towards Chris. I like him very much. I always have," Rubio told CNN. "This is a political campaign. It's a competitive environment."
