For anyone asking "what law has been broken?"
The FBI officials, DOJ Officials, The DNC, the Clinton Campaign and the Fusion GPS people (incl Ohr's Wife) could be charged with:
18 U.S. Code § 371 - Conspiracy to commit offense or to defraud United States
If two or more persons conspire either to commit any offense against the United States, or to defraud the United States, or any agency thereof in any manner or for any purpose, and one or more of such persons do any act to effect the object of the conspiracy, each shall be fined under this title or imprisoned not more than five years, or both.
Also it would be "Conspiracy to commit Fraud on the Court"
This type of fraud (submission of fraudulent and misleading documents to a court) invalidates any judgement by the court:

Further, any who submitted false information to the FBI, (Steele, Ohr's Waifu, Fusion GPS, DNC, Clinton Campaign etc) are guilty of making False Statements to a Federal Investigator (Note: the FBI and DOJ officials themselves would not be guilty under this statute due to subsection B):
18 U.S. Code § 1001 - Statements or entries generally
(a) Except as otherwise provided in this section, whoever, in any matter within the jurisdiction of the executive, legislative, or judicial branch of the Government of the United States, knowingly and willfully—
(1) falsifies, conceals, or covers up by any trick, scheme, or device a material fact;
(2) makes any materially false, fictitious, or fraudulent statement or representation; or
(3) makes or uses any false writing or document knowing the same to contain any materially false, fictitious, or fraudulent statement or entry;
shall be fined under this title, imprisoned not more than 5 years or, if the offense involves international or domestic terrorism (as defined in section 2331), imprisoned not more than 8 years, or both. If the matter relates to an offense under chapter 109A, 109B, 110, or 117, or section 1591, then the term of imprisonment imposed under this section shall be not more than 8 years.
(b) Subsection (a) does not apply to a party to a judicial proceeding, or that party’s counsel, for statements, representations, writings or documents submitted by such party or counsel to a judge or magistrate in that proceeding.
(c) With respect to any matter within the jurisdiction of the legislative branch, subsection (a) shall apply only to—
(1) administrative matters, including a claim for payment, a matter related to the procurement of property or services, personnel or employment practices, or support services, or a document required by law, rule, or regulation to be submitted to the Congress or any office or officer within the legislative branch; or
(2) any investigation or review, conducted pursuant to the authority of any committee, subcommittee, commission or office of the Congress, consistent with applicable rules of the House or Senate.
There are probably further sub charges vis-a-vis Steele's violations of confidentiality agreements, and disclosure of classified information to the media, and internal infractions against DOJ and FBI policy for those government officials involved
