President-elect Trump announced Wednesday that four senior advisers from his campaign will join him at the White House when he takes office in January.

Dan Scavino, Stephen Miller, James Blair and Taylor Budowich will all take senior staff roles in the White House, Trump said in a statement.

"Dan, Stephen, James, and Taylor were 'best in class' advisors on my winning campaign, and I know they will honorably serve the American people in the White House," he said. "They will continue to work hard to Make America Great Again in their respective new roles."

Scavino was a senior aide during Trump's first term and was a point person for the president-elect's social media presence during his four years in office. He will serve as an assistant to the president and deputy chief of staff.

Miller's role had already been reported and confirmed. He will serve as deputy chief of staff for policy and Homeland Security adviser. Miller, who was a senior adviser during Trump's first term, is expected to take on a leading role implementing Trump’s immigration agenda, which includes plans for mass deportations of immigrants without legal status.

Blair was the campaign's political director, overseeing Trump's unorthodox ground game to reach low-propensity voters. He will join the White House as deputy chief of staff for legislative, political and public affairs.

Budowich previously ran Trump's main super PAC, MAGA Inc., before joining the campaign over the summer. He will serve in the White House as deputy chief of staff for communications and personnel.

Trump has rapidly filled out his Cabinet and senior staff this week following his election victory. He traveled to Washington, D.C., on Wednesday to meet with President Biden and with House Republicans.
