Technically no. The Feds still own the airspace. However, by issuing a TFR, they are empowering him (or other officials) to decide who is and is not considered "participating," see 14 CFR 91.137(b). So, while not technically in charge, he's effectively in charge within the TFR as he says who can and cannot participate.
