Marcus Robertson was sentenced to be released Friday morning after a federal judge ruled he does not face additional years in prison because he downloaded e-books considered terrorism material.

Robertson also known as Abu Taubah was in jail for nearly four years after he pleaded guilty of lying to FBI agents and falsifying income-tax documents. He was released on time served on non-terrorist convictions.

The sentence imposed by the judge today was 12 months, one day on the firearm charge, with 8 months on the conspiracy to submit a false claim to the United States to run consecutive to each other.  Since he has been held in custody prior to the sentencing hearing today he has served his sentence, according to the U.S. State Attorney's Office.

In 2011, the FBI found a 10,000 document Islamic library accessible from Robertson’s computer. Some of the statements made in the documents exonerate Al-Qaida’s involvement with the Sept. 11, 2001 terrorist attacks.

He was accused of training another Jonathan Jimenez on jihadi extremist tactics and would have faced 20 years in prison.

However, U.S. District Judge Gregory Presnell ruled that there was insufficient evidence to determine Robertson was directly involved with terrorism to add additional time to his sentence.

"...the prosecution has not produced one statement from Robertson himself advocating violent jihad or praising those who commit terrorism...there is no evidence to support the more significant claims Jimenez made about Robertson,” according to a sentencing memorandum signed by Presnell.
