The assimilation of the Democratic National Committee apparatus by Democratic party presidential committee candidate Hillary Clinton is underway.

According to Politico.com, Brandon Davis – the former national political director for the Services Employees International Union was named the DNC’s new chief of staff on Thursday- introduced by Hillary Clinton Campaign Manager Robby Mook at a DNC all-staff meeting.

Other changes include DNC CEO Amy Dacey’s expansion of her role to “include more general election responsibilities” an unnamed source told Politico. Also on board will be Jen O’Malley Dillon, a former Obama deputy campaign will also step up in the general election.

According to a Clinton aide the process is already underway organization-wide::

There are already people that have begun formally moving over to the DNC payroll from the Clinton campaign. That will continue. That is at various levels of seniority.”

This election cycle’s changes come a time of “deep tension” between DNC Chair Debbie Wasserman Schultz and Democratic Candidate Bernie Sanders, who has been declared loser by many news sources (Ed. Note: Not this one.) but has yet to officially pull out of the race.

Sanders has called for the replacement of Wasserman Schultz in the DNC and has endorsed the campaign of Tim Canova, who is running against Wasserman Schultz in the Florida Representative 23rd District race.

Politico quoted a Democratic Party source:

“The move that they’re making here with Amy Dacey’s expanded role, with Brandon Davis, with Jen O’Malley as an adviser, they are putting operational control of the DNC in the hands of people that they trust and fully integrating it into their operation.”

With Sanders pushing for leadership change in the party after a brutal, divisive primary, Wasserman Schultz’s future in the DNC is doubtful. Sanders said in a Tuesday press conference:

“We need a person at the leadership at the DNC who is vigorously supporting and out working to bring people into the political process”
