President Donald Trump on Monday warned that millions of undocumented immigrants in the U.S will be forcibly removed by official agencies starting next week.

In a series of tweets, on Monday evening, Trump said deporting illegal immigrants will happen at a pace “as fast as they come in.”

Trump’s hardening of stance on illegal immigrants came hours before he was to formally announce the re-election bid.

Trump said the U.S. Immigration and Customs Enforcement (ICE) would “begin the process of removing the undocumented migrants.”

An administration official told media that the drive would target more than one million people who had been illegally staying back in the country despite getting formal legal orders to leave.

Political analysts do not miss the political message behind the crackdown on undocumented immigrants.

In 2016, Trump floated his poll campaign by committing a hard line on illegal immigration, raising a wall in the southern border with Mexico and removal of undocumented immigrants.

In this latest U.S immigration news, Trump’s plan of deporting millions of people would pose a big challenge to the resources of ICE which is already strained by the influx of migrants who cross the border illegally.

Mass arrests likely

According to reports, the background planning for removing illegal immigrants had been in the works for some time.  

Trump and his immigration adviser Stephen Miller wanted Homeland Security officials to arrest and overthrow of thousands of family members served with deportation orders by the Justice Department. The operation has been named “rocket docket.”

In April, Trump removed acting ICE director Ronald Vitiello and Homeland Security Secretary Kirstjen Nielsen following their reluctance to go ahead with the Trump plan.

They had reservations over preparation for the drive and the backlash from the public on issues like children being taken into custody or separated from families.

In the reshuffle at ICE former FBI and Border Patrol official Mark Morgan replaced Vitiello. The former was able to impress Trump with his strategy on hard enforcement.

Mark Morgan, ICE's new acting director recently said the agency is studying options to arrest and deport families already ordered to exit.

The operation would target migrants with a “final order of removal,” according to Morgan. He said deportation is essential to reduce the incentive for potential migrants crossing over to the United States.  Donald Trump President Donald Trump speaks to media prior to his departure from the White House on November 20, 2018, in Washington, DC to his Mar-a-Lago resort in Palm Beach, Florida, for the Thanksgiving holiday.

Former Homeland Security Secretary Kirstjen Nielsen was against the plan saying the department’s priority will be to deport criminals.

Many in the Trump administration believe that a show of force including mass-arrests would deter potential illegal immigrants and they think twice on journeying into the U.S illegally as the effort will not pay off.

Trump’s rally in Florida to kick start the second bid

Meanwhile, Donald Trump will be launching his 2020 re-election campaign in Florida on Tuesday.  

In the re-election bid, Trump is trying to project himself as a winner and administrator of great self-confidence.

On Tuesday, Trump will address a big crowd of over 20,000 people at the Amway Center in Orlando, Florida.

Trump tweeted that the rally “looks to be setting records”, adding that "Our Country is doing great, far beyond what the haters & losers thought possible – and it will only get better!”

Despite the winner’s bravado, data from pollsters at Quinnipiac University show that the president is trailing behind many Democrats in terms of the following percentage.

Joe Biden 53: 40, Bernie Sanders 51: 42, Kamala Harris 49: 41, Elizabeth Warren 49: 42, Pete Buttigieg 47: 42 and Cory Booker 47: 42.
