WASHINGTON (AP) — The founder of one of the oldest and largest charter school networks in the District of Columbia used a for-profit management company he owns to funnel millions of school funds to himself, according to a legal complaint filed Monday.

The allegations, filed by D.C. Attorney General Irvin Nathan, center on Kent Amos, who founded Dorothy I. Height Community Academy Public Charter School as a nonprofit organization in 1998. The group serves more than 1,600 students at four campuses and an online school.
