  The majority of the highest energy cosmic rays are thought to be electrically
charged: protons or nuclei. Charged particles experience angular deflections as
they pass through galactic and extra-galactic magnetic fields. As a consequence
correlation of cosmic ray arrival directions with potential sources has proved
to be difficult. This situation is not helped by current data samples where the
number of cosmic rays/source are typically < O(1). Progress will be made when
there are significantly larger data samples and perhaps with better catalogs of
candidate sources. This paper reports a search for correlations between the
RXTE catalog of nearby active galactic nuclei, AGNs, and the published list of
ultra-high energy cosmic rays from the AGASA experiment. Although no
statistically significant correlations were found, two correlations were
observed between AGASA events and the most inclusive category of RXTE AGNs.
