Chicago Mayor Rahm Emanuel says his fundraising has helped a pro-Obama super PAC keep its ads on television in the campaign's final weeks.
Speaking to reporters at Bloomberg offices Thursday, Emanuel couldn't say how much money he has brought in, but said "I've done my job."
He later said he has raised "enough that they're on the air."
Emanuel is a former Obama chief of staff. He was a national campaign co-chairman until early September, when he stepped down to fundraise for the pro-Obama super PAC Priorities USA Action.
The PAC's fundraising report for September isn't due until later this month.
Emanuel says he believes the president performs best in tight contests with time running out, adding "this is his kind of environment."
Emanuel also said he's hitting the campaign trail for Obama, noting he will do "whatever it takes" to get the president re-elected.
The mayor said individual organizations have asked him to campaign in other states. His staff couldn't immediately confirm the times and places.
