Over the next several days, the Senate will debate the composition of President-elect Donald Trump’s cabinet, starting with one of their own: Sen. Jeff Sessions (R-Alabama), Trump’s nominee for attorney general.

All nominees have been vetted by the Federal Bureau of Investigation, the Internal Revenue Service and the Office of Government Ethics and an ethics official from the department they’re nominated to lead, prior to the hearings. The next step is up to senators. The Senate committees relevant to the nominee in question—Sessions, for example, will be evaluated by the Judiciary Committee—can either vote to move the nomination to the Senate floor or opt not to vote, essentially rejecting the nomination. If the committee approves, the nominee must receive a simple majority vote by the full Senate. 

After Sessions’ first hearing by the Committee on the Judiciary at 9:30 a.m. Tuesday, the Committee on Homeland Security and Governmental Affairs will discuss at 3:30 p.m. whether retired Marine Corp. General John Kelly is an acceptable appointment for head of the Department of Homeland Security. Those curious about what the Senate has to say about each of Trump’s picks can tune in to the Senate’s website for broadcasting its hearings.

The hearing dates and times have frequently been shuffled in the days leading up to the Senate votes, but here is an up-to-date schedule of this week’s hearings: 

Jeff Sessions, attorney general: Tuesday, 9:30 a.m. and Wednesday, 9:30 a.m.

John Kelly, secretary of homeland security: Tuesday, 3:30 p.m.

Betsy DeVos, secretary of education: Wednesday, 10 a.m.

Michael Pompeo, Central Intelligence Agency director: Wednesday, 10 a.m.

Elaine Chao, secretary of transportation: Wednesday, 10:15 a.m.

James Mattis, secretary of defense: Thursday, 9:30 a.m.

Ben Carson, secretary of Housing and Urban Development: Thursday, 10 a.m.

Wilbur Ross, secretary of commerce: Thursday, 10 a.m.

Following this week’s discussions, Senate committees will decide on Trump’s nominations of South Carolina Gov. Nikki Haley for ambassador to the United Nations, Exxon Mobil Corp. Chief Executive Rex Tillerson for secretary of state, CKE Restaurants Chief Executive Andy Puzder for secretary of labor, former Goldman Sachs investor and hedge fund manager Steven Mnuchin for secretary of the treasury, Oklahoma Attorney General Scott Pruitt for head of the Environmental Protection Agency and U.S. Rep. Tom Price (R-Georgia) for secretary of the Health and Human Services Department.
