  The behavior of the conductivity and the density of states, as well as the
phase relaxation time, of disordered itinerant electrons across a quantum
ferromagnetic transition is discussed. It is shown that critical fluctuations
lead to anomalies in the temperature and energy dependence of the conductivity
and the tunneling density of states, respectively, that are stronger than the
usual weak-localization anomalies in a disordered Fermi liquid. This can be
used as an experimental probe of the quantum critical behavior. The energy
dependence of the phase relaxation time at criticality is shown to be that of a
marginal Fermi liquid.
