When GOP congressional aides gather Tuesday morning for a meeting of the Conservative Working Group, Samuel Joseph Wurzelbacher – more commonly known as Joe the Plumber — will be their featured guest. This group is an organization of conservative Capitol Hill staffers who meet regularly to chart GOP strategy for the week.

Wurzelbacher, who became a household name during the presidential election, will be focusing his talk on the proposed stimulus package. He's apparently not a fan of the economic rescue package, according to members of the group.

If nothing else, GOP aides are using the appearance to get staffers to attend the 9 a.m meeting.

“In case you weren’t planning to attend CWG tomorrow morning, you might want to reconsider because Joe the Plumber will be joining us!” Kimberly Wallner, an aide to South Carolina Sen. Jim DeMint, wrote in a message to her e-mail list this afternoon.
