ABC News has identified three of the people subpoenaed by the New Jersey Assembly special investigative committee, according to sources familiar with the legislative probe.
They are former Christie deputy chief of staff Bridget Kelly, former Christie campaign manager Bill Stepien and current Christie press secretary Michael Drewniak.
ABC News has learned that 17 individuals and three organizations were among those subpoenaed.
The rest of the names have not been released.
Committee Chairman John Wisniewski earlier said the committee "has no intention right now to subpoena the governor." That echoes comments made by him and others in recent days, saying that going right after Christie would be "premature."
Wisniewski said the subpoenas have return dates in early February and he doesn't anticipate the committee meeting again until mid-February.
The closures near the George Washington Bridge were apparently ordered as political payback and caused massive traffic backups.
