Craigslist and eBay have agreed to stop selling scalped tickets to the presidential inauguration, Chuck Schumer, the chair of the Joint Congressional Committee on Inaugural Ceremonies, announced today.

Soon after the tickets began being distributed, Schumer’s committee became aware that the tickets were being sold on eBay and Craigslist and began lobbying the websites to block the sales.

The tickets, many of which are marked “not for sale,” are distributed through government officials. They are not sold.

eBay will block listings of the tickets on its site, and Craigslist has said its staffers will monitor the site and remove such listings, according to a statement from the committee.

Some items were still for sale on Craigslist and eBay, however, and many Craigslist users had resorted to posting that they wanted to buy tickets.
