Senate candidate Joe Sestak (D-Pa.) missed his own campaign rally, featuring former President Clinton, in order to vote for a state-aid bill in the House.

Sestak, a two-term lawmaker, was in D.C. for the vote, instead of at the campaign rally in Scranton, reports NBC's First Read

The rally with Clinton was scheduled last week, before Speaker Nancy Pelosi (D-Calif.) recalled lawmakers to Washington to vote on a $26 aid package to states. The Senate passed the bill last week, which provides $16 billion in Medicaid funding and $10 billion to prevent teacher layoffs.

Sestak taped a message for the crowd in Scranton, and then Clinton, along with Sestak's wife and daughter, took the stage.

Sestak faces a tough general election campaign against Republican Pat Toomey. Sestak became the party's nominee after defeating Sen. Arlen Specter (D-Pa.) in the May primary.
