The House Intelligence Committee subpoenaed the FBI and Department of Justice for documents about a controversial dossier that linked President Trump to Russia.

The committee issued the two identical subpoenas on Aug. 24, requesting that both agencies hand over documents containing information about the dossier, the FBI’s relationship to its author and whether the FBI had supported an opposition research project against Trump in the last months of the 2016 presidential campaign, the Washington Examiner reported Tuesday.

The subpoenas set a deadline of Sept. 1 for the documents to be handed over, but it was extended to Sept. 14 after both departments missed the deadline, according to the Examiner.
