For the second month in a row, the number of unaccompanied children crossing the border has decreased.

On Monday, the Department of Homeland Security announced that last month, the number of minors caught crossing the border alone was at its lowest since February 2013, NBC News reports. In August 2014, Border Patrol agents apprehended 3,141 children.

In May, 10,580 children were caught at the border, and in June the number rose to 10,622.

In addition, the number of families found crossing the border decreased to 3,295. The number had reached its peak in June with 16,329 families.

As the numbers decrease, political tension increases.

In a Monday interview with MSNBC, Cecilia Muñoz, Obama's domestic policy director, said that the "situation at the border that happened over the summer has been really, really heavily exploited by folks on the other side of the aisle ..."

Muñoz also criticized the Republican Party, who she said used to create immigration policies, but has now changed.

"[There is now] a Republican House that the only thing they passed with respect to immigration had to do with deporting DREAMers, young people brought to this country as infants and small children who know no other country but this one," she said. "That's a pretty profound change that demonstrates the political maelstrom we're in."

Obama has stated that he will not take action until at least after Nov. 4, which is Election Day.

The delay has some threatening not to vote, however.

"Maybe only by paying a price at the polls will Democrats finally stop throwing us under the bus," Carmen Velasquez, founder and retired executive director of Alivio Medical Center in Chicago, wrote for Politico.

White House press secretary John Earnest has stated that Obama will act by the end of 2014.

"The White House raised hopes in the Latino community that they would take action before the midterm election, and now that they are delaying the decision, polling data suggests Latino voters will be less enthusiastic about turning out to vote in November," Matt Barreto, co-founder of Latino Decisions and a political science professor at the University of Washington, told Fox News Latino.

On Tuesday, the Colorado Immigrants Rights Coalition will hold a rally outside of Colorado Sen. Michael Bennet's office, "to express the anger and disappointment in ... the role of Senate Democrats in asking Obama to delay executive action for political reasons."

"Our coalition is outraged by President Obama's continued lies and betrayal of the hard working, contributing immigrants who are the fabric of this country," Sonia Marquez, Colorado Immigrant Rights Coalition Action Fund's north region organizer, said. "He has dragged us along for far too long with his false hopes and false promises."
