D.C. police spokesman Lt. Nicholas Breul said Arenstein and his wife were arrested early Saturday and charged with possession with intent to distribute marijuana.
Breul says vice units had received a complaint of marijuana growing in the couple's backyard. Police then obtained a search warrant for the home in northwest D.C.
Breul says officers found large, mature cannabis plants, standing more than 8 feet high. In addition, they found packaged marijuana inside the home.
According to the CBS News website, Arenstein serves as radio bureau manager for CBS News, Washington.
A CBS News spokeswoman declined to comment.
