The Clinton Foundation accelerated its fund-raising in the first six months of the year, officials said Thursday, as Hillary Rodham Clinton was gearing up for her presidential run amid a crush of news reports scrutinizing the charity’s solicitation of foreign donors.

Foundation officials said there were 10,516 donors so far this year, compared with 8,801 during the same six-month period last year.

The Bill, Hillary and Chelsea Clinton Foundation did not release the precise amounts any donor gave or the total raised. Rather, it posted on its website a newly updated cumulative list of contributors, most of them dating to 2001. The amounts are listed in ranges; the highest tier is $25 million and up.

Among the names that surfaced as donors for the first time was that of the golfer Tiger Woods, who was listed as having given $25,001 to $50,000.
