Some of the migrants making their way through Mexico en route to the United States are suing President Donald Trump, saying their Constitutional rights are being violated over Trump's insistence that the caravans containing thousands of people will be stopped at the border.

According to Fox News, 12 migrants from Honduras — a list that includes six children — filed the lawsuit against Trump and the Departments of Homeland Security and Justice in the U.S. District Court in Washington, D.C. on Thursday. They claim their right to due process is being violated because Trump has vowed not to let the migrants into the U.S. He said people with a legitimate asylum claim will be processed and held in encampments at the border until their cases are heard.

The civil rights law firm Nexus Derechos Humanos Attorneys Inc. is funding the lawsuit, Fox reported.

Trump said Thursday he plans to end the practice of catch and release through an executive order, and will make it a requirement that asylum-seekers must come to an official port of entry. Anyone illegally entering the U.S. and asking for asylum when they're caught by the Border Patrol would be sent back to Mexico under the proposal.

The Fifth Amendment reads:

"No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offense to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation."

As many as 15,000 U.S. troops are being deployed to America's southern border to help the border Patrol deal with the influx of migrants who are expected to arrive sometime over the next several weeks.
