Just because there was no hearing does not mean that there was no FISA warrant. However, any FISA warrant would have to be signed off on by the Attorney General and would include the following:
(a) Submission by Federal officer; approval of Attorney General; contentsEach application for an order approving electronic surveillance under this subchapter shall be made by a Federal officer in writing upon oath or affirmation to a judge having jurisdiction under section 1803 of this title.

It shall include—
(1) the identity of the Federal officer making the application;
(2) the identity, if known, or a description of the specific target of the electronic surveillance;
(3) a statement of the facts and circumstances relied upon by the applicant to justify his belief that—
(A) the target of the electronic surveillance is a foreign power or an agent of a foreign power; and
(B) each of the facilities or places at which the electronic surveillance is directed is being used, or is about to be used, by a foreign power or an agent of a foreign power;

(A) that the certifying official deems the information sought to be foreign intelligence information;
(B) that a significant purpose of the surveillance is to obtain foreign intelligence information;

(9) a statement of the period of time for which the electronic surveillance is required to be maintained, and if the nature of the intelligence gathering is such that the approval of the use of electronic surveillance under this subchapter should not automatically terminate when the described type of information has first been obtained, a description of facts supporting the belief that additional information of the same type will be obtained thereafter.
