  We present the results of searches for correlation between ultra--high-energy
cosmic rays observed in stereo mode by the High Resolution Fly's Eye (HiRes)
experiment and objects of the BL Lac subclass of active galaxies. In
particular, we discuss an excess of events correlating with confirmed BL Lacs
in the Veron 10th Catalog. As described in detail in Abbasi et al. (2005), the
significance level of these correlations cannot be reliably estimated due to
the a posteriori nature of the search, and the results must be tested
independently before any claim can be made. We identify the precise hypotheses
that will be tested with independent data.
