We present a search for direct CP violation in B+/- --> J/psi K+/- and B+/- --> psi(2S)K+/- decays. In a sample of 9.7 X 10(6) B (B) over bar meson pairs collected with the CLEO detector, we have fully reconstructed 534 B+/- --> J/psi K+/- and 120 B+/- --> psi(2S)K+/- decays with very low background. We have measured the CP-violating charge asymmetry to be [+1.8 +/- 4.3(stat) +/- 0.4(syst)]% for B+/- --> J/psi K+/- and [+2.0 +/- 9.1(stat) +/- 1.0(syst)]% for B+/- --> psi(2S)K+/-.
