Democratic lobbyists aren’t the only K Street denizens writing checks this month to get close to senior Hill staffers.

Several Republican lobbyists are hosting a National Republican Senatorial Committee fundraiser June 23 with two dozen Senate chiefs of staff, according to an invitation obtained by Roll Call.

The price to mix and mingle with Republican staffers: $2,000 to host and $1,000 to attend for political action committees. Individuals are requested to give $500 to host and $250 to attend.

Chiefs of staff Michelle Barlow to Sen. Roger Wicker (Miss.); Tim Glazewski to Senate Minority Whip Jon Kyl (Ariz.); Kerry Feehery to Sen. George LeMieux (Fla.); and Brian Klippenstein to Sen. Kit Bond (Mo.) are among the 24 senior staffers headlining the event at Venable’s Washington, D.C., office.

The invitation also gives top billing to the senior aides’ bosses, including NRSC Chairman John Cornyn (Texas) and Sens. Lindsey Graham (S.C.), Richard Shelby (Ala.) and Chuck Grassley (Iowa).

The fete is being hosted by several K Streeters including Chad Bradley, former top aide to Sen. James Inhofe (R-Okla.), of Chad Bradley & Associates; Jeff Kimbell of Jeffrey J. Kimbell & Associates; Cesar Conda of Navigators Global; and John Green of Crossroads Strategies. Republicans Kevin O’Scannlain of DLA Piper, Matt Keelen of the Keelen Group and Pat Raffaniello of Raffaniello & Associates are also listed as hosts.

The fundraiser for GOP chiefs of staff comes on the heels of a Democratic Congressional Campaign Committee fundraiser scheduled for Thursday night. The fourth annual DCCC event at Hotel Monaco gives about 50 senior House staffers top billing. Individual attendees for that event are expected to shell out $1,000, while political action committees must give $2,500 to earn a seat at the sit-down dinner.

While Members of Congress are often used to draw in funds for the campaign committees, ethics lawyers say that there is nothing improper about using staff to draw dollars for the coffers.

An NRSC spokesman did not immediately respond to a request for comment.
