WASHINGTON: The US Senate confirmed White House deputy chief of staff Kirstjen Nielsen as Secretary of Homeland Security on Tuesday (Dec 5), putting her in charge of implementing the Trump administration's immigration crackdown.
Nielsen is close to White House Chief of Staff John Kelly, who was President Donald Trump's first secretary at the Department of Homeland Security before he was brought in to discipline Trump's chaotic office at the end of July.
Nielsen, 45, is a lawyer and veteran of the national security sector. She served in the transportation security unit of DHS during the George W. Bush administration, and was also Bush's homeland security advisor in the White House.
Later she ran her own security advisory firm, Sunesis Consulting.
Known for expertise in cyber issues, she was named Kelly's chief of staff when he took over DHS at the beginning of the Trump administration, and then followed him to the White House.
Described as tough and no-nonsense, she nevertheless lacks the experience of running a massive organization like the 240,000-strong DHS.
The agency oversees a wide range of security issues, from immigration, to cyber, terror threats and disaster relief.
The Senate approved her nomination 62-37.
Her confirmation came on a day when DHS reclaimed substantial success in slowing illegal immigration across the southern border and arresting and deporting criminal aliens.
DHS said arrests of illegal immigrants were up 40 per cent in the first nine months of the Trump administration, while border crossings plummeted based on tougher enforcement.
Trump has also ordered DHS to build a wall along the southern border.
But both Kelly and Nielsen have said that a wall on the entire 3,200-kilometre frontier with Mexico would be inappropriate, and that other measures, including electronic monitoring, would be required as well.
