Sen. Richard Burr is scheduled to appear tonight at a roundtable on health care. Admission is $2,000 a seat.

The event, which has a maximum of 35 seats, is to benefit the National Republican Senatorial Committee, reports the Sunlight Foundation's Party Blog, which tracks parties that feature members of Congress.

A more exclusive seat is available for $5,000 (limit 20).

Also attending the fundraiser are Republican Sens. Chuck Grassley (Iowa) and Mike Enzi (Wyoming).

Dome has asked Burr’s campaign office if the senator will release a list of attendees.

The Party Time blog notes that Burr's biggest donors come from the pharmaceutical and health products industry.

Update: A Burr campaign spokesman said he did not have a list of attendees handy since the event was run by the NRSC. He said he would try to get more information.
