UPDATE: The DHS this afternoon gave journalist Chris Elliott an extension until Jan. 20 to comply with a subpoena, his attorney told Tnooz. The initial deadline was Dec. 31.

Facing a Dept. of Homeland Security subpoena and its Dec. 31 deadline, travel journalist Chris Elliott has not turned over any documents related to the source who provided him with the TSA’s secret Christmas Day security directive, his attorney says.

Attorney Anthony Elia, who’s representing Elliott, says he e-mailed a request Dec. 31 to TSA special agent Robert Flaherty, who served the civil subpoena at Elliott’s home on the evening of Dec. 29, asking for “additional time to allow the process to unfold in a reasonable way.”

Giving Elliott roughly two days to respond to the subpoena was an “inordinately short” period of time and “unreasonable,” Elia says, given the serious nature of the issues.
