A professor is on paid leave for suggesting the government is responsible for the destruction of the World Trade Center.

A controversy over words at BYU this morning. A professor is on paid leave for suggesting the government is responsible for the destruction of the World Trade Center.

The man on paid leave is Dr. Steven Jones. He's a physics professor involved in the so-called "9-11 Truth Movement."

Jones believes unnamed government agencies orchestrated the fall of the twin towers and he says there's evidence to back it up.

Two weeks ago he published his theory in a paper called "Why Indeed did the World Trade Center Buildings Collapse?" In it, the professor says the towers fell not because of planes hitting them but rather pro-positioned demolition charges.

He sites research conducted at BYU on materials from ground zero, asserting those materials show evidence of thermite, a compound used in military detonations. He says terrorists could have never set those charges.

The State Department has released a rebuttal to Jones' theory in a 10-thousand page report.

BYU made this statement last night.

"Physics Professor Steven Jones has made numerous statements about the collapse of the World Trade Center. BYU has repeatedly said that it does not endorse assertions made by individual faculty.

"We are, however, concerned about the increasingly speculative and accusatory nature of these statements by Dr. Jones."

The university added, "BYU remains concerned that Dr. Jones' works on this topic has not been published in appropriate scientific venues."

It is rare for some in Dr. Jones' position to be under review because he has taught at BYU for more than a decade.

He began his career at the university in 1985 and has been known his cold fusion research. But other professors will teach his classes while he's on paid leave.

He will be allowed to conduct research in his field but the university is reviewing his actions.
