Here are some of the key Cabinet selections Trump has made and what they will oversee

 President-elect Donald Trump continues to move ahead with his presidential transition, announcing his selection for key Cabinet positions that will help carry out his policies.

Cabinet members include the vice president and the heads of the 15 executive departments in the presidential line of succession, which require Senate confirmation. Here’s a look at who Trump has picked so far — and the positions that are yet to be filled.

Below are some of the key Cabinet positions in each administration and their critical function in running the US government:

Attorney General: The attorney general’s main duty is to represent the US in legal matters as head of the Department of Justice, according to the DOJ’s website. The attorney general oversees the Federal Bureau of Investigations (FBI), the Drug Enforcement Administration (DEA), the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), among others. He or she also provides advice and opinions “on legal matters to the president and the Cabinet,” the DOJ site said. Trump has selected former Florida Rep. Matt Gaetz for attorney general, a role that is expected to be crucial to Trump’s vision for his second term and will help enforce the president-elect’s policy on immigration, reproductive health and the political retribution he’s vowed to pursue.

Secretary of State: The secretary of state is the head of the State Department, and serves as the president’s primary adviser on the country’s foreign policy and conducts negotiations relating to US foreign affairs, according to the State Department’s website. The secretary is tasked with carrying out the president’s “foreign policies through the State Department and the Foreign Service of the United States,” the department’s website said. Trump has selected Florida Sen. Marco Rubio as his pick for this high-ranking position.

Defense secretary: According to the Defense Department website, “the secretary of defense oversees the Defense Department and acts as the principle defense policymaker and adviser.” The defense secretary’s authority over the US military is second only to the president. Trump has selected Fox News host Pete Hegseth as his pick for this position.

Health and Human Services secretary: The HHS secretary advises the president
“on health, welfare, and income security plans, policies and programs of the Federal Government and directs Department staff in carrying out the programs and activities of the Department,” according to the US government manual site. The agencies and offices that fall under HHS include the National Institutes of Health, Center for Disease Control and the Food and Drug Administration. Trump has selected Robert F. Kennedy Jr. for this position.

Homeland Security secretary: The duties of this secretary’s office include counterterrorism efforts, cybersecurity, aviation security, border and port security and enforcement of US immigration laws, according to the Department of Homeland Security’s website. Trump has selected South Dakota Gov. Kristi Noem as his pick to lead the agency that’s expected to play a central role in his immigration crackdown.
