  We report progress on calculating the contribution to the anomalous magnetic
moment of the muon from the disconnected hadronic diagrams with light and
strange quarks and the valence QED contribution to the connected diagrams. The
lattice QCD calculations use the highly-improved staggered quark (HISQ)
formulation. The gauge configurations were generated by the MILC Collaboration
with four flavors of HISQ sea quarks with physical sea-quark masses.
