U.S. President Donald Trump said his administration would be taking “strong action” later Wednesday on immigration. Trump made the comment in an early morning tweet, but did not elaborate about planned steps.

Trump did, however, describe U.S. border laws as “very weak”, while saying those of Mexico and Canada are “very strong”.

The president made the comments one day after he told reporters troops are to be dispatched to America’s border with Mexico to thwart further illegal immigration, U.S.

“I think that it’s something that we have to do,” the president said in response to a question from a reporter at the afternoon event in the White House East Room.

The president and several Cabinet members, including Defense Secretary Jim Mattis, Homeland Security Secretary Kirstjen Nielsen, and Attorney General Jeff Sessions, received a briefing Tuesday to examine his administration’s strategy.

The discussion included the mobilisation of the National Guard and the need to pressure Congress to urgently pass legislation to close legal loopholes exploited by criminal trafficking, narco-terrorists and smuggling organisations.

The Pentagon responded to Trump’s plan to use the military to guard the borders.

“We are still consulting with the White House,” a senior defense official said, promising more information.

Two of Trump’s predecessors — George W. Bush and Barack Obama — sent National Guard units to provide intelligence, surveillance and reconnaissance support for Border Patrol agents.

An opposition Democratic Party senator, Brian Schatz of Hawaii, who serves on the defense subcommittee of the Senate’s appropriations committee, quickly criticised the idea, stating on Twitter that “Our military has more important things to do than to be mobilised to fulfill” a campaign promise of Trump’s.

In the United States, the active duty military is generally restricted from domestic law enforcement functions, which would include capturing people who have come across the borders.

At the news conference, the president also spoke of a “caravan” of more than 1,000 migrants from Central America that has been making a 2,000-kilometer [1,200 mile] journey from the Mexico-Guatemala border to the United States. He has mentioned the procession several times on Twitter in recent days, vowing that it must be stopped.

In the past several days, the caravan has been mentioned numerous times on the Fox News Channel, which is Trump’s preferred source of broadcast news.

Those in the caravan “thought they were going to just walk right through Mexico and right through the border” into the United States, explained Trump, who praised a quick response from Mexico, which he said was acting to ensure it is “all being broken up.”

Mexico has reportedly offered some of the migrants refugee status. (VOA)
