Our country is being robbed," says Trump about illegal immigrants

US President asks Congress to pass anti-immigration legislation and threatens to expel Mexico from trade agreement if country does not strengthen border

The president of the United States , Donald Trump , asked on Monday Congress to pass legislation anti-immigration , a day after saying that not cogitará an agreement to protect young immigrants and which will close a trade pact with Mexico if the neighbor not to further protect the border .

"Congress must immediately approve border legislation, use the 'nuclear option' if necessary, to stop the mass influx of drugs and people ... now, Congress, our country is being robbed!" Trump tweeted. The nuclear option is a parliamentary procedure that, in practice, allows the Senate to decide an issue by simple majority.

One of his tweets apparently referred to a group of 1,500 men, women and children from Honduras, Guatemala, and El Salvador who are traveling in a so-called "refugee caravan" organized by the People Without Borders, an immigration advocacy group with headquarters in the United States.

One of Trump's top campaign promises was to build a wall on the southern border of the United States and insist that Mexico pay for it - which the Mexican government refuses to do.

Trump said he was open to negotiating with Congressional Democrats to receive funding for the wall in exchange for protection for young immigrants who entered the country as children, the so-called dreamers.

Former President Barack Obama launched the program in 2012. Trump canceled it in October, but courts have ruled that it may remain in effect for now.

The US is also involved in the renegotiation of the North American Free Trade Agreement (NAFTA) with Mexico and Canada.

Despite Trump's concessions to Democratic parliamentarians on immigration, no agreement has yet been signed. The Senate, which is controlled by the Republicans, studied several proposals linked to the issue in February, but rejected all.

In the early months of Trump management, the number of people who crossed the border illegally and were seized receded, but from April 2017 increased and surpassed that of the Obama administration.
