Laura Ingraham said she believes liberals are using the controversy over migrant family separations at the border to push for their real goal: a borderless world.

President Donald Trump on Wednesday signed an executive order to allow children to stay with parents caught crossing the border illegally -- moving to stop the family separations that have triggered a national outcry and political crisis for Republicans.

In response, many Democrats -- including House Minority Leader Nancy Pelosi (D-Calif.), Sen. Bernie Sanders (I-Vt.) and Sen. Chuck Schumer (D-N.Y.) -- slammed the order, which they claim allows illegal immigrants to be detained indefinitely.

In her "Angle" monologue Wednesday night, Ingraham noted that under a 1997 Supreme Court decision, the government is prohibited from keeping children in immigration detention longer than 20 days.

"If families aren't separated and can't be housed together, we have one humongous catch-and-release nightmare on our hands," Ingraham said. "Basically, it means any alien with a child will get a fast pass into the country."

She said President Trump tried to send a strong message that America will not tolerate "border crashers" by prosecuting anyone who violated federal law by entering the country illegally.

Ingraham noted that almost immediately after Trump signed the executive order, some on the left have already moved on to their next mantra: "We shouldn't be detaining anyone."

"They want to show the American people that borders themselves are fundamentally unjust, they're a violation of human rights."
