WFTV has learned federal prosecutors think a man from Orlando is putting the government informant who gave him up in an alleged terrorist plot in life-threatening danger.

Imam Abu-Taubah, aka Marcus Robertson, is accused of training Jonathan Paul Jimenez, who had moved to central Florida from New York, in skills necessary to "participate in violent jihad overseas," skills like martial arts, firearms and knife training.

Federal prosecutors said Robertson, a convicted felon, is telling people the name and description of the confidential informant in the case, and the information comes at a time when prosecutors said there's a plot to kill the informant.

According to documents, during a recorded call, Jimenez told a confidential government source that Robertson told him "it was permissible or obligatory to kill members of the armed forces, specifically generals" and that Robertson showed him what a general's stars look like.

Jimenez also was recorded saying Robertson told him suicide bombings were "permissible," according to documents.

Now, federal prosecutors said Robertson "has in his correspondence from jail identified a confidential source” and spread information about the confidential informant's identity.

WFTV legal analyst Bill Sheaffer said the court documents are crafted very carefully to withhold sensitive information. 

“Because the case implicates the highest level of national security, the government is going to keep this evidence as much as possible, shrouded in secrecy,” Sheaffer said.

Robertson's attorney filed a 25-page document, describing Robertson as a holy man who was only trying to help Jimenez out of a life of crime and give him religious instruction.

The document challenges federal prosecutors to provide more evidence than just Jimenez's secretly recorded statements, which would show Robertson really did conspire with Jimenez to kill U.S. military overseas.

Jimenez and Robertson are charged with tax fraud, which the FBI said was intended to pay for their international terrorism scheme.      

Sheaffer believes federal prosecutors have more evidence than what they've made public so far.
