The subpoenas^ were issued by Mike Conaway (R-TX) who sought basic information about the Steele dossier that we still do not know. Such as who paid for it.
The consensus has long been that an Anti-Trumper initially funded the Steele dossier through the primary. But then pro-Clinton supporters forces took over funding. There are even claims that the FBI paid Fusion GPS as well for this "dossier" the contents of which have never been substantiated.
Despite this lack of substantiation, the FBI was somehow able to use it to get a FISA warrant. This warrant allowed the Obama Admin to wiretap the Trump campaign under false cover in one of the most outrageous acts in US election history. It also seems almost certain that the Obama folks then passed on some of the FISA-acquired information to aid the Clinton Campaign.
