NEW YORK, November 11. /TASS/. US President-elect Donald Trump will launch the largest mass deportation operation of illegal immigrants in American history on his first day in office, Trump Transition Spokeswoman Karoline Leavitt told Fox News.

"On day one, he’s going to launch the largest mass deportation operation of illegal immigrants in American history," she pointed out.

According to Leavitt, Trump is ready to take action to secure the US southern border - "something that the Biden-Harris administration has refused to do."

Trump defeated current US Vice President Kamala Harris, the Democratic Party’s contender, in the November 5 presidential election. The Republican Party took control of the Senate and is also expected to gain a majority in the House of Representatives. Trump’s inauguration is set for January 20, 2025.
