Members of the Islamic State (ISIS) and al-Qaida terror groups are in the U.S. and thirsting to stage a 9/11-style attack, says Jim Gilchrist, president of The Minuteman Project, which monitors illegals flowing into the country from Mexico.
"I have no doubt that there are elements of al-Qaida and ISIS scattered throughout the country," Gilchrist said Tuesday on "The Steve Malzberg Show" on Newsmax TV.
"There aren't enough of them to reap the havoc in the United States that they have done in Syria and in Iraq. All they have to do is carry out another 9/11 and that's their intention."

And Gilchrist believes the terrorists will try to go for big numbers in any assault.
"I don't think they're targets are El Paso or Brownsville, Texas, or San Diego, California.
They want the big body targets," he said.
"They want an elementary school with 800 kids killed. They want a synagogue or a cathedral … with 5,000 people killed on a Saturday or Sunday. They want a large body count. This is what they seem to prefer."
The Islamic State, more radical than al-Qaida, has been slaughtering Christians in Iraq in its plan to establish a religious caliphate that will eventually rule the world.
In recent weeks, it has released videos showing the grisly beheadings of American journalists James Foley and Steven Sotloff.
Gilchrist said the U.S.-Mexico border is anything but secure from members of terror groups from sneaking in.
"No one is keeping tally of who's coming in or out of that border. Of course, more people by the millions are coming in from the Mexican border than are being deported back out," he said.
"The border patrol apprehends only about one out of four of those persons attempting to enter the United States through that border with Mexico.
"I estimate about 2.4 million people have come across into the United States and are currently here just in the last fiscal year bringing a total of illegal aliens occupying U.S. territory to a little over 30 million."
Gilchrist is wary of President Barack Obama's potential executive order on immigration reform, which would grant amnesty to illegal immigrants.
"This is a politically inspired ploy by the Democratic Party and it's been going on for decades to lure as many people from all around the world," he said.
"My immigration legal advisor councils me … [that] five years after amnesty is given to the illegal aliens, they will become voting citizens and more likely than not at least 90 percent are going to support the Democratic Party.
"And for the first time in the history of the United States, we will be a solid, one party system. It's the same kind of system that they have in China."
