"Having a ticket to the inauguration is a privilege, it's not something that should be used to make a profit," he said on Monday.

The Hill reported last week that Craigslist had ads hawking the tickets, which are free to the public through congressional offices.

The scalping isn't technically illegal, but is frowned upon.

"We've asked the online dealers in these tickets not to sell them. Stubhub has cooperated but today I'm renewing my call, asking actually Craigslist and eBay not to sell inaugural tickets for money through an auction. That is their civic duty," said Schumer, the chairman of the Joint Congressional Committee on Inaugural Ceremonies (JCCIC).

He said Craigslist and eBay have not responded to his pleas: the committee has heard "nothing," he said. "That's the problem. So we're asking again."

Schumer's renewed push came in part because of The Hill's report, according to a source in the JCCIC.

The inaugural tickets — all 250,000 of them — are distributed through congressional offices. House members received the tickets on Monday. Senators will receive them on Tuesday.
