The FBI has now made official statements (as opposed to the leaks that they have been feeding the press) regarding the San Bernardino shooters, and there was no proclamation of support for ISIS or any other terrorist group on social media:

There is no evidence a married couple who killed 14 people in California this month were part of a terrorist cell, the head of the FBI said on Wednesday, echoing investigators’ views that the pair were inspired by, rather than organized by, Islamic State in Iraq and Syria (ISIS).

………

However, he said that while the perpetrators of the Dec. 2 shootings in San Bernardino, Calif. — Syed Rizwan Farook, 28, and Tashfeen Malik, 29 — had expressed support for “jihad and martyrdom” in private communications, they never did so on social media.

Just days after the attack, authorities said they were looking into an apparent Facebook post in which Malik had pledged allegiance to ISIS leader Abu Bakr al-Baghdadi.

Multiple U.S. media outlets reported Malik had expressed “admiration” for al-Baghdadi, but it was under an account that used a different name. The messages were reportedly deleted before the attack, and Facebook quickly removed the account in the wake of the shooting.

Seriously, why does the press continue acting as the FBI’s stenographer when the senior officials who leak this crap could not be trusted if they said the sky was blue?

When you get repeatedly burned by a source, they are no longer a source, they are just a random asshole for whom you refuse to take off the record statements.
