Minnesota Gov. Tim Pawlenty will become the first major political leader on Wednesday to hold a town hall meeting via Facebook.

The event will begin at 7:15 p.m. eastern time and last half an hour. The format allows the potential 2012 GOP presidential hopeful to appear live on camera, with attendees sending questions for him to respond to in real time.

A source close to Pawlenty also said the governor will make a major announcement about his political action committee's activities.

Pawlenty has made strides to be at the front of the 2012 pack when it comes to new media.
