President Obama is expected to visit Portsmouth, N.H. on Friday for a campaign event. 

Obama will be joined by First Lady Michelle Obama, Vice President Joe Biden and Dr. Jill Biden during what the Obama campaign is describing as a "grassroots event" at the Strawberry Banke Museum. 

The campaign has announced that tickets are available for the free event, which begins at 10 a.m. To pick up a ticket, members of the public can visit the Obama For America office in Portland. The office is located at 533 Forest Ave between 5 p.m. Tuesday and 8 a.m. Wednesday.
