  We give an update on the status of the Fermilab Lattice-HPQCD-MILC
calculation of the contribution to the muon's anomolous magnetic moment from
the light-quark, connected hadronic vacuum polarization. We present
preliminary, blinded results in the intermediate window for this contribution,
$a_{\mu, \textrm{W}}^{ll}$. The calculation is performed on $N_f =2+1+1$
highly-improved staggered quark (HISQ) ensembles from the MILC collaboration
with physical pion mass at four lattice spacings between 0.15 fm and 0.06 fm.
We also present preliminary results for a study of the two-pion contributions
to the vector-current correlation function performed on the 0.15 fm ensemble
where we see a factor of four improvement over traditional noise reduction
techniques.
