Another surge of illegal immigrant minors was reported in March at the Mexico-U.S. border.

According to a new report from the federal government, the number of minors apprehended last month was the highest since last summer at more than 3,000.

The numbers are only expected to grow as the weather gets warmer, but the surge is not expected to surpass last summer's unprecedented influx.

More than 15,000 unaccompanied minors have been apprehended during the current fiscal year, which began Oct. 1, 2014. Nearly 14,000 family units were taken into custody in that time period. 

Bill Hemmer discussed the new data with Fox Business Network's Lou Dobbs this morning. Dobbs said the continuing issues result from the Obama administration's "invitation" to children to come to the U.S. illegally, while the border remains "utterly insecure." 

He said the numbers are lower than 2014, but appear to be "building" and now it is expected that this summer will bring a repeat of what happened last summer.

Hemmer pointed out that human traffickers know our laws and are marketing the fact that illegal immigrants could be allowed to stay in the U.S. once they arrive.

"ICE has been pulled back. They can't even go after these folks. It's creating a huge morale problem. In point of fact, our laws are not being enforced and our borders are wide open," said Dobbs, pointing out that the administration could use taxpayer money to fly children into the United States after their parents enter the country illegally.

"What's really dangerous is that we've got a government that's not accountable to anyone right now," said Dobbs.
