We study the charged cosmic rays arising from the slow decay of gravitino dark matter within
supersymmetric scenarios with trilinear R-parity violation. It is shown that operators of the
LLE type can very well account for the recent anomalies in cosmic ray electron and positron data
reported by PAMELA, ATIC and Fermi LAT, without violating any other bounds. This scenario
will soon be tested by the Fermi LAT data on diffuse gamma ray emission.
