The Senate confirmed President Trump’s pick to lead the Department of Homeland Security (DHS) after John KellyJohn Francis KellyMORE left the agency for his White House post earlier this year.

Senators voted 62-37 on Kirstjen Nielsen’s nomination to be DHS secretary, with 10 Democratic senators and Independent Sen. Angus KingAngus Stanley KingLindsey Graham: Trump firing Mueller would 'probably' be impeachable offense Angus King: McCabe firing seemed 'mean-spirited' With bills on the table, Congress must heed the call to fix our national parks MORE (Maine) siding with Republicans to support her. 

Nielsen, who was nominated in October, was expected to secure confirmation after clearing a procedural hurdle in a 59-33 vote on Monday evening.

She’ll be the department’s first Senate-confirmed secretary in months. Kelly left to become Trump’s chief of staff in July, and Elaine Duke has led the agency in an acting capacity since then.

Republicans have praised Nielsen, a cybersecurity expert and former Homeland Security official.

Senate Majority Leader Mitch McConnellAddison (Mitch) Mitchell McConnellCollins: 'Extremely disappointing' ObamaCare fix left out of spending deal House poised to vote on .3T spending bill Budowsky: Stop Trump from firing Mueller MORE (R-Ky.) urged senators to back her nomination ahead of Tuesday’s vote.

“It’s time for us to vote to confirm her so she can get to work for the American people. By confirming Ms. Nielsen’s nomination to lead DHS, the Senate will take a serious step to strengthen our nation’s security. [She] will be charged with leading the department at a critical time,” he said from the Senate floor.

But Democrats raised concerns during her confirmation hearing about her lack of leadership experience, noting that DHS is a sprawling agency with roughly 240,000 employees.

“Why should we believe that, as smart as you are, and as well-spoken as you are, that someone who, as far as I know, never led an organization of even 100 people, much less 240,000, is ready to take on this responsibility?” Sen.

Nielsen’s nomination was also held up for a week in the Homeland Security and Governmental Affairs Committee after members sent her more than 200 requests for follow-up information.

Nielsen previously served on George W. Bush’s homeland security council. She also worked with Kelly at DHS when he served as secretary earlier this year, and followed him to the White House to become his chief of staff.

As DHS secretary, Nielsen will head an agency charged with protecting America’s borders, squashing cybersecurity threats and leading the response to natural disasters.

Her position will also drop her into the middle of multiple immigration fights, as senators debate how to address the Deferred Action for Childhood Arrivals (DACA) program.

The Trump administration announced in September it would end the program, which allows certain immigrants brought into the country illegally as children to live and work.

Congress has until mid-March to pass a legislative fix to give DACA new life, or hundreds of thousands protected under the program would face deportation.

In addition to DACA, DHS is at the center of battles over a U.S.-Mexico border wall and the Trump’s administration travel ban. The Supreme Court handed Trump a win on Monday by granting his administration’s request to fully reinstate the third version of his travel ban.

Trump pledged during his presidential campaign to build a U.S-Mexico border wall. But Nielsen told the Senate’s homeland security panel that “there is no need for a wall from sea to shining sea.”
