TUCSON, Ariz. (AP) - Attorneys are scheduled to deliver closing statements on Friday in the criminal trial against a humanitarian aid volunteer who says he was fulfilling his duty to help others when he encountered two migrants near the U.S.-Mexico border.

The trial against 36-year-old Scott Daniel Warren has drawn condemnation from human rights groups who say President Donald Trump's administration is increasingly targeting border activists.

Federal prosecutors allege Warren conspired to harbor two immigrants, saying they weren't in distress when Warren provided them with food and shelter in a building used to aid sick migrants who have just crossed into the U.S.

Border Patrol agents arrested Warren in 2018.

Warren is one of several volunteers recently charged with misdemeanors related to their border work, although he alone faces felony counts.
