Jeb Bush told about 350 of the top donors to his super PAC on Sunday evening that the organization has raised more money in its first 100 days than any other Republican operation in modern history, according to several people in attendance.

Bush did not say how much had been raised, but senior Republicans said they think his super PAC, Right to Rise, is on track to collect $100 million by the end of May. Those who heard Bush speak said it signals that he and his team are confident that they’ve amassed a sizable political fortune that will help bankroll his fledgling presidential aspirations.

Until now, George W. Bush has held the record for the best presidential fundraising debut of a GOP candidate. In the first four months of 1999, he brought in close to $37 million.
