Goodell and several league officials walked into the Austin office about 7:15 p.m. Saturday for what was expected to be a private two-hour meeting. He and the league have been heavily criticized for how they handled the recent suspension of Baltimore Ravens running back Ray Rice, who punched his then-fiancee in the face.
Asked for comment, Goodell only said he's "doing the work, as they say" and that he was invited to visit the hotline.
The hotline was founded in 1996 and is housed in an unmarked building.
Goodell met with 11 former players earlier this week and was told the league must act immediately when someone is accused of domestic violence.
