The deployment of more than 5,000 troops the U.S. southern border is a political stunt by President Trump ahead of the midterms, Judith Miller said Tuesday.

The troops are being sent as reinforcements as the roughly 4,000-strong migrant caravan slowly makes its way through Mexico and toward the United States.

Miller -- a Pulitzer Prize-winning reporter and Fox News contributor -- questioned why the troops are being sent to perform logistical and support functions. 

"They're not going to protect the border," she said. "They're going to help move things around."

President Trump has repeatedly called for the caravan to retreat, tweeting on Monday that the U.S. military is "waiting" for them.

Miller said that the deployment is a "terrible misuse" of federal funds and conservatives should be "furious" about the waste of resources.

"This is the kind of stunt that doesn't pass the smell test," she said.

Currently, about 2,000 National Guard troops are assisting those already at the border.

The Wall Street Journal's Dan Henninger disagreed with Miller's outlook, saying that the troops will "disincentive" the migrants from advancing to the border.

"I think sending that many troops down there [and saying] 'please do not come across that border' is not the worst idea."
