A group of officials including former Foreign Minister Jorge Castañeda hopes to cause distress for the already-backlogged US immigration courts by encouraging migrants to fight their cases in court

Mexican officials, legislators, governors and public figures are pushing back against Trump's antagonistic stance toward their country.

Means include increasing the 'backlog in the immigration system' and defending undocumented migrants in the US and the Wall Street Journal reported.

Other proposed measures include renegotiating deals such as the one that currently makes Mexico accept deportees from the United States without proof that they are Mexican.

This comes as Donald Trump continues to demand Mexico pay for his much vaunted border wall, to renegotiate NAFTA, and his promises of aggressive deportations.

Mexican senator Arturo Zamora told the Journal: 'We want to be friends, but in the face of continued hostility we don't have to keep a friendly attitude forever.'

A group of officials including former Foreign Minister Jorge Castañeda hopes to cause distress for the already-backlogged US immigration courts by encouraging migrants to fight their cases in court.

This comes as Donald Trump antagonizes Mexico through, for example, his plans to build a border wall with Mexico - which could cost $22bn or more - and make Mexico pay for it, to renegotiate NAFTA, and his promises of aggressive deportations

The group coined itself as Monarca, after the butterflies that migrate across North America.

While emigrants might be detained for months during the court process, Castañeda said measures such as government funds going to legal representation or paying bail could speed up the process.

Meanwhile, the Mexican government has assigned $50m in assisting undocumented migrants in the United States as the Mexican Foreign Ministry responds to 'the hardening of measures by immigration authorities in the U.S., as well as possible constitutional violations during raids or in due process.'

Mexican Prime Minister Enrique Peña Nieto has met with deportees at Mexican airports after cancelling a planned trip to Washington to meet Trump in late January.

Trump has said that the U.S. Congress should fund his wall up-front, but that Mexico will reimburse U.S. taxpayers. Mexico has said it will not pay.
