The new chairman of the Republican National Committee is spending the majority of his workday courting donors as he seeks to rebuild the organization's credibility.

"I am spending 5-6 hours a day on the phone raising money and we have gotten our mail program back up and running the way it should be," Reince Priebus, chairman of the RNC, told The Political Insider, a conservative publication. "We have work to do but we have taken great steps in the right direction with both mail and rebuilding relationships with major donors."

Many in the Republican donor community soured on the committee during former chairman Michael Steele's reign because of a perceived misuse of funds

Priebus, who has been on the job for about three months, said raising money was his main focus and predicted President Obama will "run the first billion dollar campaign" in 2012.

"We need to match him dollar for dollar," he said. "If he can spend $750 million to $1 billion dollars in messaging to try and mask and undo the fiscal realities of where we are in this country, that’s why the money issue is going to be our biggest challenge."
