YORK, Maine (AP) — Vice President Joe Biden is scheduled to attend a private fundraiser in Maine for New Hampshire Gov. Maggie Hassan, a Democrat who is due to run for re-election next year.

Biden is scheduled to attend the event Thursday at the York home of New Hampshire Democratic lobbyist James Demers. However, he currently is in Houston with his son, Delaware Attorney General Beau Biden, where the younger Biden is undergoing medical tests. It's not clear how long the vice president will stay with him.

The Maine fundraiser is being hosted by Demers, former Maine Gov. John Baldacci and Maine lobbyist Severin Beliveau.
