"He thanked me for my friendship, my support, he said we're gonna work together as a Republican Party and we're gonna get the best man in office and he doesn't want to stand in the way of that," Gamache said.
Pataki failed to gain any significant traction in public polls, only rarely topping one percent measured support since getting into the race.
He participated in several network undercard debates but lacked the support to qualify for the prime-time stage in any of the race's five debates to date. He also failed to make the primary ballot in key states like Ohio and Texas.
The former New York governor used his undercard appearances to take aim at Donald Trump. In September, he called Trump "unfit to be the president of the United States or the Republican nominee."
In the latest fundraising quarter, Pataki only raised about $153,000, including a significant loan from the candidate himself.
