EDITOR'S NOTE: RESENDING STORY TO CLARIFY INCOMING INTERIOR MINISTER'S COMMENTS RULING OUT SPECIFICALLY "SAFE THIRD COUNTRY" STATUS.

The journey of migrants heading for the U.S.-Mexico border hit another roadblock on Saturday.

This after Mexico's incoming government denied there being an agreement with the Trump administration for a plan that would have asylum seekers wait in Mexico while their claims are processed in the U.S. That plan - reported by the Washington Post - would effectively end the "catch and release" system long criticized by U.S. President Donald Trump that allows those seeking refuge to wait on safer U.S. soil.

The Post had reported that the government of President-elect Andres Manuel Lopez Obrador originally backed the plan, known as "Remain in Mexico." But incoming interior minister Olga Sanchez Cordero later said the plans to assume "safe third country" status were ruled out.

She called the ongoing talks, quote, "very delicate." Lopez Obrador will take office on December 1st.

He's vowed to create more jobs and improve living conditions to stem migration.

Trump, meanwhile, on Twitter Saturday threatening to close the southern border, saying there's no way that the U.S. will "put up with this costly and dangerous situation anymore."
