We point out a possible association of high-velocity molecular gas wit
h the Galactic center radio lobe (GCL). A molecular spur in the easter
n GCL ridge is receding at V-LSR similar to +100 km s(-1), and the wes
tern spur approaching at V-LSR similar to -150 km s(-1), suggesting a
high-velocity rotation of the GCL. We study the kinematics of the GCL
based on these molecular line data.
