A major terror group pledges allegiance to ISIS.
Egyptian militants, who until now had been solely fighting their government are taking up the cause. The group calls on "god's chosen fighters" to join what they call the war against Islam.
"In obedience to God and his prophet, who warned against division among his people, we are announcing our allegiance to the Caliphate," militant said in audio recording.
The group is considered Egypt's most dangerous militants. Dissatisfied with al Qaeda, they are now turning to ISIS. The affiliation is expected to provide new money, weapons, and soldiers.
There's also concern the group could adopt ISIS tactics of terrorizing civilians and tourists with indiscriminate killings and beheadings.
Experts say it's a major victory for ISIS in the propaganda war.
But ISIS isn't only gaining support in Egypt. CNN's Jim Sciutto has more on how far ISIS' global reach extends.
Is the president's war against ISIS illegal?
Senator Rand Paul believes it is. The Kentucky Republican, who is eyeing a presidential run, wrote an op-ed in The Daily Beast, saying: "...this war is now illegal. It must be declared and made valid, or it must be ended. Congress has a duty to act, one way or the other."

The United States is doubling the number of troops on the ground in Iraq. The Pentagon said Friday it's sending up to 1,500 to help Iraqi troops who continue to struggle against ISIS with large sections of the country under militant control.
The Pentagon spokesman insisted to CNN that this latest ramp up is not mission creep.
"It's not mission creep at all," Rear Admiral John Kirby said. "Mission creep is when the mission changes or morphs into something that it didn't originally start out to be. This is very much in keeping with the missions that we have been performing in Iraq since June."
So if it's not mission creep, then what?
In June, President Barack Obama sent 300 advisers to Iraq. In September, he laid out a limited military engagement against ISIS with a pledge that it would not involve American troops fighting on the ground.
U.S. officials insist the troops are in a non combat role, but with the additional troop numbers there will be some 3,000 U.S. soldiers in Iraq - on the ground and in harm's way.
In interview with CNN's Erin Burnett, Democratic Congressman John Garamendi, who is also a member of the House Armed Services Committee says Congress was informed about the additional troop deployment.
ISIS is advancing in Iraq, despite weeks of U.S. airstrikes. The terror group is only about eight miles from Baghdad's airport. Secretary of Defense Chuck Hagel said Friday that a key province in Iraq is in trouble of falling. ISIS has been bearing down on Iraqi forces in Anbar province just west of Baghdad.
CNN's Jim Sciutto has the latest.
There were 11Â new U.S. airstrikes against ISIS in Syria and Iraq - six of those strikes near the besieged city of Kobani.
But still, ISIS now appears to be in control of a third of this key city near the Syria – Turkey border.
Airstrikes alone aren't turning the tide.
And Turkey, a key U.S. ally in this fight, says it's not realistic for the world to expect Turkey to fight the ground war alone.
But as the battle continues, it's now a race against time to rescue an American held by ISIS.
