We present preliminary measurements of D to K0L pi and D to K0S pi branching fractions using 281 pb-1 of psi(3770) data at the CLEO-c experiment. We find that BF(D0 to KS pi0) is larger than BF(D0 to KL pi0), with an asymmetry of R(D0) = 0.122 +- 0.024 +- 0.030. For BF(D+ to KS pi+) and BF(D+ to KL pi+), we observe no measureable difference; the asymmetry is R(D+) = 0.030 +- 0.023 +- 0.025. Under reasonable theoretical assumptions, these measurements imply a value for the D0 to K+- pi-+ strong phase that is consistent with zero. The results presented in this document are preliminary.
