Speaker Nancy Pelosi (D-Calif.) is scheduled to host a fundraiser for her party’s nominee in the special election in Pennsylvania’s 12th district — a competitive, conservative district previously represented by of one of her closest confidants, the late Rep. John Murtha (D).

Pelosi and Democratic Congressional Campaign Committee Chairman Chris Van Hollen (Md.) will host a reception for Mark Critz, a top Murtha aide who is vying to succeed his boss in the May 18 special election. The event is scheduled for Tuesday evening in Washington, D.C.

Tickets cost from $1,000 to $5,000 for political action committees and from $250 to $2,400 for individual guests.

Critz faces businessman Tim Burns (R) in the special election, which is the same day as the state’s regularly scheduled primaries.
