  We establish a small time large deviation principle and a Varadhan type
asymptotics for Brownian motion with singular drift on $\bR^d$ with $d\geq 3$
whose infinitesimal generator is $\frac12 \Delta + \mu \cdot \nabla$, where
each $\mu_i$ of $\mu = (\mu_1, \cdots, \mu_d)$ is a measure in some suitable
Kato class.
