The caravan of Central American migrants that President Trump has portrayed as an emblem of flawed immigration policy in the United States began to splinter on Thursday, as hundreds of people departed from this rural town aboard buses and on foot, abandoning the decrepit municipal sports complex where their journey had stalled for five nights. Mexico has long made use of its own military on its borders - and incursions by the Mexican military into the US have sparked worldwide incidents.
Trump has stepped up his anti-immigration rhetoric recently.
"We will not allow illegal immigration levels to become the norm", she said.
He also announced earlier this week that he would send troops to the border to prevent illegal crossings.
Investors in Mexico's beaten-down equity market got some more relief Wednesday as escalating trade tension between the world's two largest economies took the spotlight off of U.S. President Donald Trump's protectionist stance toward his country's southern neighbor.
Marine Lt. Gen. Kenneth F. McKenzie told reporters at the Pentagon Thursday that it has not yet been determined how many, if any, of the National Guard troops participating in the border security operation will be armed. Trump said he was directing Defense Secretary Jim Mattis and Homeland Security Secretary Kirstjen Nielsen, in coordination with Attorney General Jeff Sessions, to come up with an "action plan" within 30 days.
One of those candidates said Mexico should restrict its cooperation with the US on anti-terrorism efforts until the troops are withdrawn.
CNN reported organizers of the 1,100-person march planned to break into smaller groups.
Trump adds that "Border crossings are at a still UNACCEPTABLE 46 year low".
The president said that the nation's security was under threat from "drastic illegal activity", including drug smuggling.
The governor says he's been in touch with Homeland Security Secretary Kirstjen Nielsen multiple times this week and Arizona will cooperate fully with the Trump administration.
"The lawlessness that continues at our southern border is fundamentally incompatible with the safety, security, and sovereignty of the American people", Trump wrote Wednesday in a memo authorizing the move, adding that his administration had "no choice but to act".
