Tonight... Get on On the Record with Greta!

A Florida professor and seven other men were charged Thursday with operating a global terrorist organization.

University of South Florida professor Sami Al-Arian was shown in television images being led in handcuffs to FBI headquarters in Tampa.

"It's all about politics," the Kuwaiti-born Al-Arian told reporters as agents led him inside.

The 50-count indictment charges the eight men with operating a criminal racketeering enterprise since 1984 that supported Palestinian Islamic Jihad and with conspiracy to kill and maim people abroad, conspiracy to provide material support to the group, extortion, perjury, mail and wire fraud, obstruction of justice, attempt to procure citizenship or naturalization unlawfully and other charges.

Each defendant faces up to life in prison if convicted.

Attorney General John Ashcroft announced the arrests and spelled out the charges against the suspects at a press conference in Washington. He was to be accompanied by Paul Perez, U.S. attorney for the Middle District of Florida.

The defendants allegedly provided financial support through a number of U.S.-based entities, resolved internal conflicts, helped communicate claims of responsibility for terrorist actions and made false statements to immigration officials to help terrorists.

We'll have full details of the indictment and today's arrests including a LIVE report from Washington and a special interview with FOX News Contributor and Washington Times  investigative reporter Bill Gertz.

Plus, can we launch a military strike against Iraq without Turkey's help? It looks like the price might be too high for the United States to station troops on Turkish soil. What would we do instead? We'll talk with former Marine Lt. Col. Oliver North who is also the host of War Stories here on the FOX News Channel.
