Donald Trump’s newly installed leadership team at the Republican National Committee on Monday began the process of pushing out dozens of officials, according to two people close to the Trump campaign and the RNC.

All told, the expectation is that more than 60 RNC staffers who work across the political, communications and data departments will be let go. Those being asked to resign include five members of the senior staff, though the names were not made public. Additionally, some vendor contracts are expected to be cut.

In a letter to some political and data staff, Sean Cairncross, the RNC’s new chief operating officer, said that the new committee leadership was “in the process of evaluating the organization and staff to ensure the building is aligned” with its vision. “During this process, certain staff are being asked to resign and reapply for a position on the team.”

The overhaul is aimed at cutting, what one of the people described as, “bureaucracy” at the RNC. But the move also underscores the swiftness with which Trump’s operation is moving to take over the Republican Party’s operations after the former president all but clinched the party’s presidential nomination last week.

Trump’s campaign took over operational control of the RNC on Monday. On Friday, former North Carolina GOP Chair Michael Whatley was elected the RNC’s new chair, and Trump daughter-in-law Lara Trump was elected as co-chair. Both had Trump’s endorsement. Additionally, Trump senior campaign adviser Chris LaCivita was named as the RNC’s new chief of staff.

Whatley is replacing Ronna McDaniel, who stepped down last week after serving more than seven years in the post. Trump and McDaniel had been longtime allies, but the former president had soured on the chairperson as of late because he felt that she was not doing enough on “voter integrity”-related issues, and because she hosted Republican primary debates that she refused to participate in.

Trump advisers have described the RNC’s structure as overly bloated and bureaucratic, which they believe has contributed to the party’s cash woes. The RNC had about $8 million at the end of December, only about one-third as much as the Democratic National Committee.

Under the new structure, the Trump campaign is looking to merge its operations with the RNC. Key departments, such as communications, data and fundraising, will effectively be one and the same.
