Yes, the US Marshall Service is part of the Department of Justice.

And, although they operate under the direction of the Attorney General, the following brings up an interesting point:
The Marshals Service serves as the enforcement and security arm of the U.S. federal judiciary
If the court issues an order and the attorney general subsequently refuses to enforce that order, couldn’t the court then issue an order placing the attorney general under arrest?
Who’s going to enforce it would be the question.
US attorney general is part of Trump team.
The Marshall Service is the enforcement arm. The question is, would they refuse to do their duty?
They are under the section of us attorney general, would they even get the order? Again the attorney is party of Trump team. So no I don’t think they will enforce it even give the order to do so.
I think we’re also forgetting the US Supreme Court probably wouldn’t even do anything resembling enforcing the constitution, as demonstrated by the 5-4 decision lately (barely respected the constitution)
