TRENTON, N.J. (AP) — Gov. Chris Christie’s chief of staff has been ordered to appear before a legislative panel investigating lane closures at the George Washington Bridge.

Lawmakers announced Wednesday that they have sent a subpoena to Kevin O’Dowd ordering him to appear before the panel on Monday.

The Democrat-led panel is looking into who in the Republican governor’s administration was involved in shutting down traffic lanes near the bridge last September.

Lawmakers will likely ask O’Dowd about a meeting where another staff member said he, O’Dowd and Christie spoke briefly about the scandal last December.
