The White House, through an outside event production company called Harbinger, is soliciting corporate sponsors for this year’s Easter Egg Roll, which is prompting major concerns from ethics experts and shock from former White House officials from both parties.

The sponsorship offers range from $75,000 to $200,000, with the promise of logo and branding opportunities, according to a nine-page document sent to potential sponsors and obtained by CNN.

But the solicitation for sponsorships marks an unprecedented offering of corporate branding opportunities on White House grounds running counter to long-established regulations prohibiting the use of public office for private gain.
