Alejandro Mayorkas is the first Latino and the first immigrant to lead the Department of Homeland Security. Mayorkas is Cuban-born and was one of the original architects of the Deferred Action for Childhood Arrivals (DACA) program.

Alejandro Mayorkas is the first Latino and immigrant to be confirmed as the secretary of the Department of Homeland Security.

Secretary Mayorkas is inheriting a Trump-era DHS and is immediately getting to work to rectify issues that the Biden administration has highlighted. Two of the most pressing issues are heading up a task force to reunite migrant families who were separated by the previous administration and reviewing the "Remain in Mexico" policy.

"Remain in Mexico" is a policy that the Trump administration created and enforced that sent migrants to Mexico to await their asylum cases. The policy has been criticized both by U.S. and international politicians as a humanitarian issue.

It isn't Mayorkas' first time working for DHS.

Sec. Mayorkas was the deputy secretary of DHS from December 2013 – October 2016 under President Barack Obama. During that time, Mayorkas was crucial in responding to the 2013 – 14 Ebola virus epidemic and 2015 – 16 Zika virus epidemic. Mayorkas is ready to come back to the department and to bring back what he sees are the department's mission.

“DHS bears an extraordinary weight on behalf of the American people, the weight of grave challenges seen and unseen,” Sec. Mayorkas said in a statement. “It is the greatest privilege of my life to return to the Department to lead the men and women who dedicate their talent and energy to the safety and security of our nation. I will work every day to ensure that they have the tools they need to execute their missions with honor and integrity. The mission of the Department of Homeland Security is to safeguard the American people, our homeland, and our values. The United States is a welcoming and empathetic nation, one that finds strength in its diversity. I pledge to defend and secure our country without sacrificing these American values.”

Mayorkas is no stranger to working on America's immigration system.

Mayorkas is one of the original architects of Deferred Action for Childhood Arrivals (DACA), which is at stake because of the previous administration. The Biden administration has made a promise to preserve DACA and to create a pathway to citizenship to the 11 million undocumented people living in the U.S.

President Biden has introduced legislation to reform the current immigration system. The legislation has a timeframe for all undocumented people in the U.S. to become citizens if they follow certains steps and meet certain criteria.

While Mayorkas got bipartisan support in the Senate confirmation, some Republicans did not like his work in immigration. Sen. Marco Rubio, a fellow Cuban, voted to opposed Mayorkas.

“Not only has Mayorkas pledged to undo the sensible protections put in place by the Trump Administration that ended the dangerous policy of catch and release, but his nomination is further evidence that the Biden Administration intends to pursue a radical immigration agenda,” Sen. Rubio said in a statement.
