GRS 1758-258 and its sister source 1E 1740.7-2942 were the first objects dubbed ``micro-quasars''. Their X-ray spectra are typical of Galactic black hole candidates, and they are apparently associated with time variable cores of double-lobed radio sources, reminiscent of extra-galactic radio sources. This morphology, seen on a parsec scale within the Milky Way, earned them their nickname. Unlike the Galactic superluminal radio sources GRS 1915+105 and GRO J1655-40 more typically thought of as micro-quasars, the GRS 1758-258 and 1E 1740.7-2942 radio lobes are quite stable. This raises the possibility that the X-ray/radio source association is by chance. We have made two Chandra/HRC-I observations of GRS 1758-258 for the purposes of: (1) confirming the identification of the X-ray source with the time variable radio source, and (2) searching for arcsecond scale X-ray jets which are presumably the source of relativistic particles powering the radio lobes. First results from these observations are reported.
