President Obama is rewarding his biggest financial donors by granting them access to the White House, according to an Associated Press review.

The report shows that more than 60 of the president's biggest donors have been guests more than once. And 250 major fundraisers and donors made at least one visit to the presidential mansion.

The invitations are not illegal and they're not new. Several former presidents have done the same.

However, the practice is a departure from early in the president's term when he drew criticism for keeping financial supporters at a distance. Obama severely criticized those kinds of political perks and promised to change them.

The Associated Press report was based on a comparison on more than 470 of the president's biggest donors against logs of 2 million White House guests since 2009.
